The Easter Date

In 325CE the Council of Nicaea established that Easter would be held on the first Sunday after the first full moon occurring on or after the March equinox. From that point forward, the Easter date depended on the ecclesiastical approximation of March 21 for the March equinox. Easter is delayed one week if the full moon is on Sunday, which decreases the chances of it falling on the same day as the Jewish Passover.

Although the Council of Nicaea established the Easter date for churches around the world, not all Christian churches observe Easter according the Gregorian calendar. Many Orthodox churches still observe Easter in accordance with the Julian calendar.

In the Orthodox circles, tensions exist between New Calendarists – those who use the revised Julian calendar for calculating the feasts of the ecclesiastical year – and Old Calendarists – those who continue to use the traditional Julian calendar. The calendar question reflects the dispute between those who wish to synchronize with the modern Gregorian calendar and those who wish to maintain the traditional ecclesiastical calendar based on the Julian calendar.

There have been a number of proposed Easter date reforms. In 1997 the World Council of Churches proposed a reform to solve the Easter date difference between churches that observe the Gregorian calendar and those that observe the Julian calendar. So far, this reform has not been implemented

Symbols

Easter celebrations in Orthodox Christian communities usually include a spit-roast lamb dinner and a display of hard-boiled eggs, dyed red to symbolize the blood of Christ. The egg was an important symbol in the mythologies of many early civilizations and was also connected with the springtime fertility rituals. Many Greeks rap their eggs against their friends' eggs and the owner of the last uncracked egg is considered lucky. The red eggs are usually prepared on Holy Thursday in countries such as Greece. According to tradition, the Virgin Mary dyed eggs red to celebrate the Resurrection of Christ and to celebrate life. A traditional Easter dinner may consist of red-dyed eggs baked into a braided loaf of bread, spit-roasted, herb-perfumed baby lamb, and assorted vegetables.

One of the most common Christian symbols associated with Easter is the lamb. It is often depicted with a banner that bears a cross, and it is known as the Agnus Dei, meaning "Lamb of God" in Latin. The symbol’s origin relates to the Jewish Passover. In ancient times the Jews sacrificed a lamb in the course of the festival. The early Christians associated the sacrifice of the lamb with Jesus Christ's sacrifice on the cross. They connected the joyous Passover festival, which celebrates the liberation of Jewish people from years of bondage in Egypt, with the liberation from death represented by the resurrection of Jesus Christ.
