Easter

Easter is the oldest and most important Christian holiday, the feast of the Resurrection of Jesus Christ, an event that is the center of all biblical history.
History has not conveyed to us the exact date of the Resurrection of the Lord, we only know that it was in the spring when the Jews celebrated Pesach. However, Christians could not help but celebrate such a great event, so in 325, at the first Ecumenical Council in Nicaea, the issue with the date of Easter was resolved. By decree of the council, it was to be celebrated on the first Sunday after the spring equinox and full moon, after a full week had elapsed since the Old Testament Jewish Passover. Thus, Christian Easter is a "mobile" holiday - within the time period from March 22 to April 25 (from April 4 to May 8, according to the new style). At the same time, the date of the celebration among Catholics and Orthodox, as a rule, does not coincide.
