Historical note. Dates before the 1582 reform are shown on the Julian calendar. The astronomical positions are computed but approximate this far back β€” the lunar theory drifts by roughly a day across two millennia.

The moon behind Easter

Easter is the first Sunday after the first full moon on or after the spring equinox β€” but the Church reckons this with a tabular ("ecclesiastical") moon and a fixed equinox of March 21, not the astronomical sky. The two usually agree to the day, but not always.
