How is Easter’s date determined?
Easter is always on the first Sunday after the Paschal Full Moon, which, yes, does sound like some pagan witchcraft, but I assure you that's official church policy.
So, what's a Paschal Full Moon, you might ask? It's the first full moon after the vernal equinox. However, there's an important caveat: The church observes the vernal equinox on March 21 each year, whether it actually falls on that date or not.

In 2020, the Paschal Full Moon falls on April 7, making Easter April 12.
