Orthodox dating easter
The Orthodox Church of Finland by law follows the Western date for Easter, so they too will celebrate Pascha on March 31.). Recall that in the first three centuries of Christianity, Christians were divided about the date for celebrating the Resurrection.Some had fixed the date; others celebrated with Passover, others on a Sunday after Passover.
Being a fixed day on the old Hebrew calendar, it could fall on any day of the week.
The Holy Fire ceremony is part of Orthodox Easter rituals and the flame symbolizes the resurrection of Christ in a ceremony dating back to the 12th century.
In 1818 the Paschal Full Moon fell on Saturday March 21 (the equinox).
The reason why Orthodox and Western Christians celebrate at different times is because we still go by the old Julian calendar in calculating the date of Pascha, even though we go by the new calendar for all the fixed feasts (like Christmas and so on).
Protestants and Roman Catholics use the Gregorian Calendar for everything.
Easter will not fall as late again until 2038—a span of 95 years.
