Easter is always the 1st Sunday after the 1st full moon after the
Spring Equinox (which is March 20). This dating of Easter is based on
the lunar calendar ancient Hebrew people used to identify Passover,
which is why it moves around on our Roman calendar.
Easter can actually be one day earlier (March 22) but that is rare.
This year is the earliest Easter any of us will ever see the rest of
our lives! Only the most elderly of our population have ever seen it this
early
(95 years old or above!).
None of us have ever, or will ever, see it a day earlier!
The next time Easter will be this early (March 23) will be the year
2228 (220 years from now). The last time it was this early was 1913.
The next time it will be a day earlier, March 22, will be in the year
2285 (277 years from now). The last time it was on March 22 was 1818.
No one alive today has or will ever see it any earlier than this year!
