Calendric predictions[edit]

  • January 19, 203832-bit computer clocks overflow to represent the date as December 13, 1901.
  • 2096 will be the last leap year in the 21st century. The year 2100 will not be a leap year, as it is divisible by 100 but not by 400, and it is the first such year since 1900.
  • On March 14, 2100 (which will be February 29, 2100 in the Julian calendar), the difference between the Julian calendar and the Gregorian calendar reaches 14 days. Since 14 is divisible by 7, this will be the first time in history since its inception that the Gregorian calendar will have the same day of the week for each day of the month for the whole year as the Julian calendar. This will last until February 28, 2200 of the Gregorian Calendar.
  • 2196 will be the last leap year in the 22nd century. The year 2200 will not be a leap year, as it is divisible by 100 but not by 400, and it is the first such year since 2100.
  • FAT file systems theoretically support dates up to December 31, 2107 (though officially only up to December 31, 2099).
  • The Year type in MySQL supports dates up to December 31, 2155.
  • March 17, 2160 – Unless changes are made as to when Easter can be observed, this particular March 17 will fall within Holy Week for the first time since 2008 and fall on the same day (Monday) as it did in that year.[12]
  • Unless changes are made in the religious calendar, in 2285, the Western Easter will fall on March 22 for the first time since 1818, the earliest possible date on which Easter can occur.[13]
  • 2296 will be the last leap year in the 23rd century. The year 2300 will not be a leap year, as it is divisible by 100 but not by 400, and it is the first such year since 2200.
  • 2400 and 2800 are the century leap years in the 3rd millennium. Those are evenly divisible by 400.
  • March 1, 2800 – The Revised Julian and Gregorian calendars will differ by a day.
