When is Easter?
Type the year that you wish to find when Easter is/was
into the box on the right and press calculate:
Note: This calculator is only accurate for Gregorian
dates (years after 1582) and it will eventually become
inaccurate (after a few hundreds of thousands of years!),
since the planets rotation is slowly decreasing.
When the day that Easter falls on is plotted on a graph,
we see that Easter is a Quasicrystal.
