![]() But based on the "ecclesiastical" full moon (which occurred a day earlier) Easter occurred on the same day of the full moon, April 19.Īnd in the year 2038, the equinox falls on March 20 with a full moon the next day, so astronomically speaking, Easter should fall on March 28 of that year. In 1981, for example, the full moon occurred on Palm Sunday, April 19, so Easter should have occurred on the following Sunday, April 26. 4 (April 1973), Steven Verhezen investigated the years 1583 to 2582 and found 78 cases where the date of astronomical Easter differs from that of ecclesiastical Easter: an average of about once every 12.82 years. In the Dutch journal Hemel en Dampkring, Vol. So, in practice, the date of Easter is determined not from astronomical computations, but rather from other formulas such as Epachs and Golden Numbers. Adding additional confusion is that there is also an "ecclesiastical" full moon, determined from ecclesiastical tables and whose date does not necessarily coincide with the "astronomical" full moon, which is based solely on astronomical calculations. Hence, there can sometimes be discrepancies between the ecclesiastical and astronomical versions for dating Easter. Interestingly however, these rules also state that the vernal equinox is fixed on March 21, even though at European longitudes from the years 2008 through 2101 it occurs no later than March 20.
