About This Tool
This tool tells you which day of the week any date falls on, for dates far in the past or future. It relies on the rules of the proleptic Gregorian calendar, including its leap-year rule: a year is a leap year if it is divisible by four, except for century years, which must be divisible by 400.
Working out a weekday by hand usually means an algorithm such as Zeller's congruence or Doomsday, both of which are easy to slip up on. The calculator applies the calendar rules exactly, so it stays correct across century boundaries where the leap-year exception trips up quick mental methods.
The Gregorian calendar repeats on a 400-year cycle, so any date's weekday can be determined exactly once the leap-year rules are applied, including the century exception that trips up quick mental methods. That is why the tool stays reliable across century boundaries where shortcuts like the Doomsday rule are easiest to get wrong.
