Different aboriginal groups in Australia recognise up to 13 seasons a year depending on the region where they are from. I think that this should be noted in here somewhere.See:

== Dry Season Cool/Hot Division? ==

Why is there a division between cool dry season and hot dry season? I know it makes a difference, but there isn't any information, or articles.

== Reckoning section ==

The "reckoning" section describes the reckoning for the seasons at Denmark, USSR, Australia, UK, Ireland, traditional cultures (Northern hemisphere, East Asian, Irish), plus the Australian Arborigenes. It just misses describing it for the rest of the world... USA, Latin America, Africa and Europe. Also, no word about Mayas, Aztecs, Incas, Egyptian, Persians & other Near East cultures -- all of which acquired very sophisticated astronomical knowledge (and built huge pyramids and monumets) to track the seeasons. No word about Stonehenge either, or the other Neolithic monuments that helped track down the seasons. This is a good article, but overall I was a bit let down as I read it entirely and I still don't know when the seasons start in the USA...

::Though there are cultural claims, There are no scientific or official beginning dates of calendar seasons in the USA. Even the use of the word "astronomical" is a misnomer, as it in reality cannot distinguish the significance of a solstice or equinox as being either midpoint or beginning point.

== Does Earth's elliptical orbit influence seasons? ==

As of 15 May 2008 the article includes the following mutually incompatible statements:

"Seasonal weather differences between hemispheres are further caused by the elliptical orbit of Earth. Earth reaches perihelion (the point in its orbit closest to the Sun) in January, and it reaches aphelion (farthest point from the Sun) in July. Even though the effect this has on Earth's seasons is minor, it does noticeably soften the northern hemisphere's winters and summers. In the southern hemisphere, the opposite effect is observed."

"Compared to axial tilt, other factors contribute little to seasonal temperature changes. The seasons are not the result of the variation in Earth’s distance to the sun because of its elliptical orbit.[2] Orbital eccentricity can influence temperatures, but on Earth, this effect is small and is more than counteracted by other factors; research shows that the Earth as a whole is actually slightly warmer when farther from the sun.[3]"

Can anyone resolve this? [[User:Lfh|Lfh]] ([[User talk:Lfh|talk]]) 18:57, 15 May 2008 (UTC)

:"The Earth as a whole is actually slightly warmer when farther from the sun": This is because the northern hemisphere has more land than the southern, and land warms more readily than sea.

== "Traditional" section ==
This unsourced bit of history revision is at odds with a source at the bottom (http://www.straightdope.com/columns/read/161/is-it-true-summer-in-ireland-starts-may-1) and should be either cited or trashed. [[Special:Contributions/68.211.234.224|68.211.234.224]] ([[User talk:68.211.234.224|talk]]) 16:03, 16 December 2008 (UTC)

:Err... that actually seems to (at least approximately) agree with the content of the traditional section to me.  Perhaps you mean to say that it disagrees with the 'astronomical' section which it explicitly denies, stating that there is no scientific consensus that seasons begin on equinoxes or solstices. [[User:JulesH|JulesH]] ([[User talk:JulesH|talk]]) 19:11, 21 December 2008 (UTC)

== Diagram ==

The diagram in the astronomical section has the nearest/farthest points labelled as "[[periapsis]]" and "apoasis".  First, note that "apoasis" is a typo; the correct spelling is "apoapsis".  I would further suggest "perihelion" and "aphelion" are better terms, being equivalent terms that are both (a) better known and (b) specific to solar orbits rather than general ones. [[User:JulesH|JulesH]] ([[User talk:JulesH|talk]]) 19:16, 21 December 2008 (UTC)

== Differences in Insolation of North and South Hemisphere ==

I quote from the article:

During June, July, and August; the northern hemisphere is exposed to more direct sunlight because the northern hemisphere faces the sun. The same is true of the southern hemisphere in December, January, and February.

That is not completely correct. It's true that During June, July and August the northern hemisphere is exposed to more sunlight, and that during December, January and February the southern hemisphere is exposed to more sunlight. However, other months aren't mentioned, and one gets the impression that both hemispheres are exposed to the same amount of sunlight during other months. However, it can easily be seen that northern hemisphere is exposed to more sunlight from spring equinox to fall equinox (from the second half of March to the second half of September), and tha the southern hemisphere is exposed to more sunlight from fall equinox to spring equinox (from the second half of September to the second half of March). Thus, the northern hemisphere is exposed to more sunlight in April, May, June, July, August and September, while the southern hemisphere is exposed to more sunlight in October, November, December, January, February, and March. The insolation of the northern hemisphere peaks at the summer solstice (which coincides with beginning of astronomical Summer in the northern hemisphere), while the insolation of the southern hemisphere peaks at the winter solstice (which coincides with the beginning of astronomical Winter in the northern hemisphere), even though June and December aren't the hottest and the coldest month. I hope I pointed out the error clearly, and I'd like to suggest to the author of the piece of the article which I quoted above to correct it.  <small><span class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Stoko|Stoko]] ([[User talk:Stoko|talk]] • [[Special:Contributions/Stoko|contribs]]) 01:59, 14 April 2009 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

== problems with "Meteorological" section (under "Reckoning") ==

Reference [5] in is broken.

There is no supporting reference (citation) for the assertion (last sentence) "So, in meteorology for the Northern hemisphere: spring begins on 1 March, summer on 1 June, autumn on 1 September, and winter on 1 December", which seems to be attributed to the Societas Meteorologica Palatina, for which I notice there is a Wikipedia article in German.

== Australia - what's official about its seasons? ==

The article repeats the oft made reference in Australia to the country's "official" seasons. What makes them official? I have never seen any government publication that defines the dates. In my own curiosity about this I once asked the Bureau of Meteorology in writing and received no reply.

I contend that the dates are not official at all, just a convention. [[User:HiLo48|HiLo48]] ([[User talk:HiLo48|talk]]) 11:19, 15 October 2009 (UTC)

== Wet/dry division?  Expert probably needed here ==

I'm surprised to see there's almost no discussion of the division of time into systems of seasons other than four, and in particular the wet/dry division that typifies much of the world's climate.  (We have two seasons, wet and dry, where I live, and I live in the United States!)  I think most of the article does a very good job, but the focus on temperate seasons is a pretty serious bias.  We need an expert, or at least someone who knows more than I do, to write something about how seasons are divided into wet and dry.  I've added the expert request tag in response to this specific concern; the rest of the article is, as I said, very good.  [[User:Elliotreed|Elliotreed]] 08:28, 7 March 2007 (UTC)

I'm no expert on this, but I may have a link that will help, but it may also confuse things. See, by some reckonings, parts of Arizona (which per the page should fit into the hot rainy/dry distinction), have five seasons instead, and they don't fit the dichotomy on the page (Summer has two seasons, one dry, one wet; spring and autumn are both dry). I don't know if this helps, and I am too much of a lurker to do more than provide this, but here's more information: [http://www.desertmuseum.org/desert/sonora.php#azu Seasons in the Arizona Upland].

==Diagram in "astronomical" subsection==

The ellipse in the diagram in the astronomical subsection needs to be redrawn.  The major axis of the ellipse should coincide with the line of apsides, not with the line of solstice.  Also, the ellipse should be drawn "fat" enough that the perihelion, at one end of the major axis, is the closest point to the sun.  See the article [[Apsis]].

:Thanks for working on it.  But there is still a problem&mdash;the major axis coincides with the line of solstice, but it should coincide with the line of apsides.  I think part of the problem is the light blue border around the diagram&mdash;it is positioned horizontally, and that forces the ellipse to be positioned horizontally.  Also, the fact that the earth appears in two different sizes creates a problem.

:I suggest that if you can, you do the following:  (1) Delete the light blue border. (2) Replace the four large earths with small ones, so all six will be the same size.  (3) Move the earths at 21 June and 21 December closer to the sun.  (4) Redraw the ellipse so that its points of sharpest curvature occur at 3 July and 3 January. (So the ellipse will be tilted away from the horizontal.)  I hope this is not too hard&mdash;your work is very much appreciated!

:::Fantastic! The major axis is now correct. One more tweak and it will be just right:  The periapsis (3 January) is by definition the closest point to the sun.  To accomplish this: (1) 21 March needs to be pushed straight upward away from the sun, and 23 September needs to be pushed straight downward away from the sun.  But not so much as to alter the already correct orientation of the ellipse. (2) The sun needs to be pushed a little toward 3 January, making it off-center (since the sun is a focus of the ellipse, not the center).  (But the line of solstice still needs to go through all of 21 June, the sun, and 21 December.)  [[User:Duoduoduo|Duoduoduo]] ([[User talk:Duoduoduo|talk]]) 16:09, 28 July 2010 (UTC)

== Major modification==

The 'tilt' of the Earth does not cause the seasons,'tilt' determines whether a planet experiences equatorial or polar conditions,with the Earth biased towards the equatorial end of the spectrum.The seasons are due to the specific way the Earth orbits the Sun,this conclusion is derived by modern means which uses the power of contemporary imaging and planetary comparisons http://hubblesite.org/newscenter/archive/releases/1999/11/video/b [[User:Oriel36|Oriel36]] ([[User talk:Oriel36|talk]]) 12:52, 13 August 2009 (UTC)

The easiest means to understand why the seasons happen is through the cause of the single daylight/darkness cycle  at the geographical poles where daily rotation is absent or almost absent.At the equinoxes there is an orbital twilight or dawn where the geographical coordinates pass through the circle of illumination and those locations experience 6 months of daylight or 6 months of darkness.The cause of the seasons is that as the planet moves along its orbital circumference it does not keep the same orbital face to the Sun but changes it slowly through 360 degrees and that is why the polar twilight has its origins in the orbital motion of the Earth and not daily rotation . Once that single polar daylight/darkness cycle is explained through an actual cycle,specifically the Earth's orbital cycle,the same mechanism can then replace the old 'axial tilt' explanation for the seasons.[[User:Oriel36|Oriel36]] ([[User talk:Oriel36|talk]]) 16:55, 9 May 2010 (UTC)

Don't know how that webpage got there but it has been removed.The 'orbital face' is an awkward expression and better to get rid of it,but the description would hold for the polar coordinates which basically pivot around in a circle over the course of an annual period hence the polar day/night cycle and at lower latitudes, when combined with daily rotation,the cause the seasonal temperature fluctuations and the other issue of variations in the natural noon cycle.The time lapse footage of Uranus showing,for convenience,a North/South component of daily rotation which run parallel with the equatorial ring and the East/West component where the planet turns to the central Sun -http://hubblesite.org/newscenter/archive/releases/1999/11/video/b/ .In short,too much information is being piled into right ascension which is blocking the introduction of a proper explanation for the seasons using an orbital cycle and its characteristic turning motion to the central Sun,in the Earth's case,from a point drawn through the center of the Earth from Arctic to Antarctic circles and coincident with the circle of illumination.[[User:Gkell1|Gkell1]] ([[User talk:Gkell1|talk]]) 19:06, 7 July 2011 (UTC)

The seasons or the annual fluctuations in temperature North and South of the daily rotational equator is best explained by considering the interaction between daily and orbital dynamics with special attention given to the orbital 'traveling' axis where a planet turns to the central Sun and best understood on Earth through the polar daylight/darkness cycle.Globally,the Earth has a largely equatorial climate as the relationship between the daily rotational axis and the orbital traveling axis is just over 23 degrees while Uranus has a polar climate as the daily rotational axis is almost 90 degrees in separation from the orbital axis - http://astro.berkeley.edu/~imke/Infrared/UranusAo/ur_time_2001_2005.jpg .The common ground between planets and their respective climates is the range and intensity of temperature swings as the planet orbits the Sun,the Earth having mostly equatorial climate features experiences mild swings over large areas of the planet compared to Uranus http://climateprediction.net/images/sci_images/annual.gif [[User:Gkell1|Gkell1]] ([[User talk:Gkell1|talk]]) 07:22, 3 September 2011 (UTC)

== Start of the Seasons ==

It seems over the last few years people have been trying to change the date that a season begins. This is especially true if an equinox or solstice falls late in the day. For example the March equinox recently fell on March 20, 2011 @ 23:21 UT. Since it was late in the day, many referred to March 21 as the first "full day" of the season. Not so: in the Gregorian calendar, the first day of a season is '''not''' required to be an integer - ''and never has been!'' The first day of a season is the date of the equinox or solstice. Nothing more - nothing less - no matter what local time it falls. So in this example the first "full day" of Spring for the Northern Hemisphere was March 20 - not the 21st.  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/68.196.122.36|68.196.122.36]] ([[User talk:68.196.122.36|talk]]) 02:24, 22 March 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

This is horses for courses and no need to fret over the start of the seasons.Those who live in areas of the world where there are large swings in temperature between summer and winter such as New York while the fluctuations between daylight and darkness is of less relevance will opt for the solstices and equinoxes as an anchor for when the seasons start and end while the Western isles of Europe where there are fairly large  seasonal swings in daylight/darkness hours and not so much focus on temperature fluctuations,the beginning of the calendar months are most favorable given that it places December 21st roughly in the middle of winter.Astronomers work within more restrictive guidelines as the seasons are demarcated by hemispheres while the root cause of both daylight/darkness asymmetries and temperature fluctuations require global solutions and cannot be conveniently explained by hemispherical means.This issue is important for many reasons,not least the contentious issue of 'what is a planet' and why flexibility is required sometimes.[[User:Gkell1|Gkell1]] ([[User talk:Gkell1|talk]]) 07:45, 3 September 2011 (UTC)

== serious error in "Astronomical" section (under "Reckoning") ==

This section needs to be largely rewritten, since it implies that the thermal lag for continental climates is <i>greater</i> than for oceanic climates, when in fact it is <i>the other way around</i>! My guess is that the convention of starting seasons at the solstices and equinoxes began in (north?)western Europe (under which I include the British Isles), which has a more oceanic climate with <i>greater</i> thermal lag than most of North America because of the general west-to-east movement of air masses. The first paragraph could be repaired by replacing "continental" with "oceanic". The last sentence, however, is almost complete rubbish. To retain it in recognizable form it would have to look something like this:

The oceanic climate of the southern hemisphere produces a longer temperature lag; despite that, the start of each season is usually considered to be several weeks before the respective solstice or equinox in this hemisphere, as in some countries with continental climates and in cultures with Celtic roots.

There is also no citation for the first two sentences of the last paragraph.

:<small> ''... late relpy ...''  No, the southern hemisphere definitely has a shorter seasonal temperature lag (see any seasonal data for places there).  I see why you make the claim about [[thermal lag]], but thermal capacity doesn't seen to dictate how it works with the seasons.

It is unhelpful as the 'Heliocentric view of the seasons' article doesn't reflect an accurate view of the seasons nor its cause.A recent and more reasoned approach does not dwell on the 'no tilt/no seasons' aspect but rather re-directs rotational inclination towards planetary climate as being equatorial,polar of somewhere in-between.For instance,the climate of Uranus is almost totally polar due to its inclination while the Earth has a largely equatorial climate hence the 'no tilt/no seasons' perspective fades into obscurity.[[User:Gkell1|Gkell1]] ([[User talk:Gkell1|talk]]) 13:31, 2 January 2012 (UTC)

== Seasons in Montreal (Koppen Hemiboreal Zone) ==

Hi, this is meant to be a comment, I do not want this to appear on the main page (I'm not too certain how Wikipedia works).

I live in Montreal, which is located in Koppen's Hemiboreal climate zone.  I've always found that the traditional 4 seasons never fit Montreal's climate, and probably best fit the climate of Mediterranean Europe (esp. Greece and Italy).  In Montreal, we realy have 6 seasons:

Winter is associated with heavy snow, and generally begins in mid-December and ends in late March or early April;

Then we have the Spring Melt season ("le dégel" in French), which lasts a few weeks and can occur anytime in March or April. This season is often associated with Spring flooding;

After that we have Spring which goes into mid-May or early June, which is the season when the leaves come out and the spring flowers bloom;

Summer is associated with hot weather, when you don't need to wear a jacket and it's warm enough to go swimming.  This lasts from late June to late August or early September if you're lucky.  Most people try to have a two to three week vacation during this period.  Quebec's official construction holliday usually takes place during the last two weeks of July, which is the hottest time of year, and many people not part of the construction industry also take their vacations at the same time.  In most offices, people take staggered vacations such that up to a quarter of personnel may be on vacation during this season;

Then you have a fall or harvest season, that starts in early September, and includes the leaves changing colour (which is especially dramatic in October)and falling. The beginning of this season is often called "la rentrée" in French, because that's when the school year begins and the new year also begins in entertainment and in politics.  It's also the date when most people have taken their summer vacations, so offices are fully staffed again;

Finally you enter our 6th season, which I call the "Grey" season, in which most of the leaves have fallen, and we are waiting for the first major snow fall of Winter.  This rather depressing period usually includes November and early December.  It's often rainy and overcast;

This 6-season division is probably most appropriate for the Koppen Hemiboreal climate Zone. I believe it should be possible to define "natural" seasons for most climate zones that do not necessarily fit the traditional four seasons that best describe the climates of Southern and Western Europe.

2. If so, why?
This is not an earth shattering, life altering issue for me, but would be another bit of trivia for my cesspool(sp?) of useless information(Ha,Ha!) So, thanks to anyone for posting the answer to these questions.

== Earth’s Rotation and its Orbital Motion ==

Following are the two types of motion of earth (No need to go in detail)

# Axial Motion: Spinning of earth around its own axis
# Orbital Motion: Revolution of earth around the sun in its orbit 

Both #1 and #2 are independent of each other. 

For simplicity, lets the tilted axis of the earth remains vertical when the earth rotates and orbits around the sun.  Thus days and nights are 12 hours each on the equator of the earth. Follow any '''point X''' (say Sunrise on Sep 22) on the equator of earth on the images of earth as shown in the [https://www.google.ca/search?q=earth+seasons+rotation&source=lnms&tbm=isch&sa=X&ved=0ahUKEwinqbn6gKnYAhVO6mMKHfDnBZwQ_AUICigB&biw=1280&bih=699#imgrc=vkXwKu0ee-XZlM: diagram] [The similar diagrams in sec 1.1 of the article do not match with the Google diagram for seasons on earth]

Bird’s Eye Observer of the diagram notices on '''point X'''

* Sunrise on Sep 22 
* Midnight on Dec 21 
* Sunset on March 21 and 
* Noon on June 21

This means Sunrise and Sunset flip after every six months. The same explanation is also applied to sidereal time. 

Similarly, if earth rotates once in about 24 hours '''with respect to the sun''' (Article of Wikipedia [[Earth's rotation]], third paragraph) then 

# Exactly on what specific point on spherical sun though it shines outwardly in every direction 
# Aforesaid two types of motion of earth dependent on each other 
# There is a problem with the speed of rotation of earth when the aforementioned '''point X''' (Noon on June 21) always facing the sunshine after about 24 hours when the earth rotates and revolves around the sun.

Conflict arises if clocks are adjusted relative to the sun and a star at the same time. Things are approximate for understanding purpose

1. Earth completes its rotation w.r.t sun in 24 hrs (approx.)

2. Earth completes its rotation w.r.t star in 23 hrs 56bmin

Difference in one complete rotation = 4 min


Both the solar noon and sidereal noon coincide on the equator of earth on March 01. Now

'''Relative to sun / clock adjusted w.r.t sun

March 01

Start a stopwatch at solar noon

Sidereal noon appears after 23 min 56min

Solar noon appears after about 24 hrs.

Difference = 4 min

March 02

Start a stopwatch watch again at solar noon

The fixed point of the sidereal noon appears after 23 min 56min but its not a real point anymore relative to star

Solar noon appears after about 24 hrs.


'''Relative to star/ clock adjusted w.r.t Star
'''

March 01

Start a stopwatch at sidereal noon

Sidereal noon appears after 23 min 56 min

Solar noon appears after about 24 hrs.

Difference = 4 min

March 02

Start a stopwatch again at sidereal noon

Sidereal noon appears after 23 min 56min

The fixed point (24 hrs reference) of the solar noon appears after about 24 hrs but its not a real point anymore relative to sun

So this means we can’t adjust our clocks at the same time relative to sun and a star

: ... so we choose to use the sun (averaged).  What's the problem?

== Nonsensical wording ==

''Calculation based on data published by Jones et al. [15] ]]''</br>
Can someone rewrite this? I [https://en.wikipedia.org/enwiki/w/index.php?title=Season&type=revision&diff=970227485&oldid=968736672 have corrected some parts].--[[User:Adûnâi|Adûnâi]] ([[User talk:Adûnâi|talk]]) 01:41, 30 July 2020 (UTC)

== Basic difference  tropical / temperate seasons ==

Definition in 1rst sentence says "A season is a division of the year marked by changes in weather, ecology, and the amount of daylight." In the tropics there is no amount of daylight connected to seasons. It is basically about dry and wet seasons (and cooler and hotter, not depending on the small difference in daylight length). The article is biased -as mentioned before - to the situation in the temperate zones. 

I am writing from Tanzania (-2 to -10 degrees). Difference in daylight is nearly 50 min in the south, in the north much less during the year. Seasons do not depend on this difference. So sentence 1 is wrong. The article needs a different approach. [[User:Kipala|Kipala]] ([[User talk:Kipala|talk]]) 18:35, 4 October 2020 (UTC)

:approach like this looks more appropriate: https://www.newworldencyclopedia.org/entry/Season
:"''A season is one of the major divisions of the year, generally based on yearly periodic changes in weather. 
:''In '''temperate and polar regions''', four seasons are generally recognized: spring, summer, autumn or (fall), and winter.
:''In some '''tropical and subtropical regions''', where the amount of precipitation varies more dramatically than the average temperature, it is more common to refer to a rainy (or wet, or monsoon) season and a dry season. In other tropical areas, three types of seasons are recognized: hot, rainy, and cool.
:''In some parts of the world, special "seasons" are loosely defined, based on significant phenomena, such as a hurricane season, tornado season, or a wildfire season.''"[[User:Kipala|Kipala]] ([[User talk:Kipala|talk]]) 11:09, 5 October 2020 (UTC)

:By now it has been deleted, and the [[Mawsim (disambiguation)|DAB page dealing with the Arabic/Muslim concept of "season"]], which offers a bit of info on the side, is now also [[Wikipedia:Articles for deletion/Mawsim (disambiguation)|proposed for deletion]]. The redirect was plain wrong, I remember now, but what's wrong with having anything on the topic of "Mawsim (season)", dealing with the Arabic and, by acculturation through Islam, the wider Muslim world? Why not start smth new? I'm short on time, but maybe someone else is interested? [[User:Arminden|Arminden]] ([[User talk:Arminden|talk]]) 20:01, 30 July 2022 (UTC)

== Nothing on cultural & historical aspects ==

Ironically, the only section not dealing with natural science aspects is on the military use of seasons.

Different civilisations have and have had very different approaches. The topic is huge, yet there's absolutely nothing on it. The Arabic/Muslim term ''mawsim'' has been brought up here-above, but there is so much more. Human life rotates around seasons.
