A common year is any year that has exactly 365 days, and so is not a leap year. For example, the years 2025, 2026, and 2027 are common years. Also, century years like 1800, 1900, 2100, 2200, and 2300 that are not divisible by 400 are common years in the Gregorian calendar. Those century years are also called exceptional common years.

Types of common years

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

Starting on Sunday

For such a year, the dominical letter is B and a Friday the 13th occurs on May 13. Such years occur 43 times in the 400-year cycle of the Gregorian calendar and 3 times in the 28-year cycle of the Julian calendar.

Century 01–28 29–56 57–84 85–99

300–399 310 321 327 338 349 355 366 377 383 394

In the Julian calendar, such years occur when the year reduces to 1, 7, or 18 mod 28.

This type of common year last occurred in 2022 (2 years ago) and will next occur in 2033 (9 years from now).

Finding repeating calendar years

Next repeating calendar year

For most common years, the following method for finding the next repeating calendar year will work.

Take the year mod 4. Then, if the result is

  • 1, add 6 years.
  • 2 or 3, add 11 years.

For example, the calendars for the years 2025, 2026, and 2027 repeat in 2031 (6 years later), 2037 (11 years later), and 2038 (11 years later) respectively.

The only exceptions occur whenever a century year is not a leap year. In that case, for 8 of the 11 consecutive years up to and including that century year, do the following to find the next repeating calendar year:

  • Add 12 years if the year ends with "90", "91", "97", or "98".
  • Add 6 years if the year ends with "94", "95", "99", or "00".

For example, as the year 2100 is not a leap year, the calendars for the years 2090, 2091, 2097, and 2098 repeat in 2102, 2103, 2109, and 2110 (12 years later) respectively; while the calendars for the years 2094, 2095, 2099, and 2100 repeat in 2100, 2101, 2105, and 2106 (6 years later) respectively.

Last repeating calendar year

For most common years, the following method for finding the last repeating calendar year will work.

Take the year mod 4. Then, if the result is

  • 1 or 2, subtract 11 years.
  • 3, subtract 6 years.

For example, the calendars for the years 2025, 2026, and 2027 repeat those of 2014 (11 years earlier), 2015 (11 years earlier), and 2021 (6 years earlier) respectively.

The only exceptions occur whenever a century year is not a leap year. In that case, for 8 of the 11 consecutive years starting with and including that century year, do the following to find the last repeating calendar year:

  • Subtract 6 years if the year ends with "00", "01", "05", or "06".
  • Subtract 12 years if the year ends with "02", "03", "09", or "10".
