A leap year checker tells whether a selected year has 365 or 366 days. It is useful for school work, calendar planning, February 29 birthdays, anniversary dates, scheduling, and checking century years such as 1900, 2000, or 2100. The checker uses the Gregorian calendar rule: years divisible by 4 are usually leap years, years divisible by 100 are not, unless they are also divisible by 400. Enter a year and review the result with rule checks, February length, and nearby leap years.
The year 2000 is a leap year because it is divisible by 400. The year 1900 is not a leap year because it is divisible by 100 but not by 400.
Century years are the easiest place to make mistakes, so the 400-year rule matters.
