Leap year

A leap year is any year that has exactly 366 days, including February 29 (known as Leap Day). For example, the years 2020, 2024, and 2028 are leap years. Years that are not leap years are known as common years.

In the Julian calendar, leap years occur every 4 years without exception. On the other hand, in the Gregorian calendar, leap years usually still occur every 4 years, except that century years (those that end with "00") are not leap years unless they are divisible by 400. So, the years 2000 and 2400 are leap years, while the years 1800, 1900, 2100, 2200, and 2300 are not leap years. Century years divisible by 400 are also called century leap years.

It has often been proposed (by John Herschel and others) that years divisible by 4000 should not be leap years. But the 4000-year rule has never been officially adopted, so the years 4000 and 8000 are still considered to be leap years.

Types of leap years

There are 7 types of leap years, one for each day of the week.

In the tables of occurrences in the 400-year cycle below, leap years that are 96 years apart are aligned within the same column to maintain a consistent pattern.

For such a year, the dominical letter is BA, February 29 is on a Tuesday, and a Friday the 13th occurs on October 13. Such years occur 13 times in the 400-year cycle of the Gregorian calendar and once in the 28-year cycle of the Julian calendar. Any century leap year (divisible by 400) in the Gregorian calendar will always be such a year.

0–99 0 28 56 84

200–299 220 248 276
300–399 316 344 372

In the Julian calendar, such years occur when the year reduces to 24 mod 28.

This type of leap year last occurred in 2000 (24 years ago and the last century leap year until the year 2400) and will next occur in 2028 (4 years from now).

Finding repeating calendar years

For most leap years, just add 28 years to find the next repeating calendar year. For example, the calendars for the years 2004, 2008, 2012, 2016, 2020, 2024, and 2028 repeat in 2032, 2036, 2040, 2044, 2048, 2052, and 2056 (28 years later) respectively.

The only exceptions occur whenever a century year is not a leap year. In that case, for the leap years ending with "72" to "96" preceding that century year, do the following to find the next repeating calendar year:

  • Add 40 years if the year ends with "72", "76", "80", "84", or "88".
  • Add 12 years if the year ends with "92" or "96".

For example, as the year 2100 is not a leap year, the calendars for the years 2072, 2076, 2080, 2084, and 2088 repeat in 2112, 2116, 2120, 2124, and 2128 (40 years later) respectively; while the calendars for the years 2092 and 2096 repeat in 2104 and 2108 (12 years later) respectively.
