It must be specified in the Gregorian calendar, extended to all epochs using linear year numbering: use the proleptic Gregorian calendar in Christian Era before the change, and the astronomical year convention (using negative numbers, and year 0) in all years BC before the Christian era (there's a difference of 1 in absolute value).
In the Gregorian calendar, the standard calendar in most of the world, [6] almost every fourth year is a leap year. Each leap year, the month of February has 29 days instead of 28. Adding one extra day in the calendar every four years compensates for the fact that a period of 365 days is shorter than a tropical year by almost six hours. [7]
On a non-Leap Year, some leapers choose to celebrate the big day on Feb. 28. Some choose to celebrate on March 1. Some even choose both days or claim the whole month of February to celebrate.
If the year can be evenly divided by 100, it is not a leap year unless the year is also evenly divisible by 400, according to mathisfun.com. For example, 2000 and 2400 are leap years, but 1800 ...
If a year is divisible by 100 but not divisible by 400, we skip the leap year. For example, 2000 was a leap year but 1700, 1800, and 1900 were not. The next skipped leap year will be in 2100.
{{IsLeapYear|year}} year defaults to {{CURRENTYEAR}} (2024). It must be specified in the Gregorian calendar, extended to all epochs using linear year numbering: use the proleptic Gregorian calendar in Christian Era before the change, and the astronomical year convention (using negative numbers, and year 0) in all years BC before the Christian era (there's a difference of 1 in absolute value).
The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.
A year may be a leap year if it is evenly divisible by 4. Years divisible by 100 (century years such as 1900 or 2000) cannot be leap years unless they are also divisible by 400. (For this reason ...
