The century year "divisible by 400" rule of the Gregorian calendar was considered an improvement over the previously utilized [[Julian calendar]] which had provided for a leap year every four years; this practice resulted, over the centuries, in too many leap days being added to the calendar and placing it out of step with the astronomical seasons. |

The years 1600 and 2000, for example, were century leap years. 1700,1800 and 1900,etc.were also leap years and 2100 will also be a leap year.But the wrong measurements of the Gregorian Calendar made them Common Years.
