Easter falls on the first Sunday after the Full Moon date, based on mathematical calculations, that falls on or after March 21. If the Full Moon is on a Sunday, Easter is celebrated on the following Sunday.
How is the date for Easter worked out?
The simple standard definition of Easter is that it is the first Sunday after the full Moon that occurs on or after the spring equinox. If the full Moon falls on a Sunday then Easter is the next Sunday.
Why is Good Friday not on the same date?
According to the Bible, Jesus Christs death and resurrection occurred at the time of the Jewish Passover, which was celebrated on the first Full Moon following the vernal equinox. This soon led to Christians celebrating Easter on different dates.
Why is it called the Paschal moon?
The paschal full moon is the ecclesiastical full moon of the northern spring and is used in the determination of the date of Easter. The name paschal is derived from Pascha, a transliteration of the Aramaic word meaning Passover. The first day of each of these lunar months is the ecclesiastical new moon.
How is the date of Good Friday decided?
Good Friday is the Friday before Easter, which is calculated differently in Eastern Christianity and Western Christianity (see Computus for details). Easter falls on the first Sunday following the Paschal Full Moon, the full moon on or after 21 March, taken to be the date of the vernal equinox.
