Easter - a celebration of Resurrection of our Savior Jesus Christ, and is the most important day in the Christian liturgical year, often called the Feast of Feasts.
Easter is celebrated on Sunday immediately following the first Spring full Moon that comes on or after the Vernal (Spring) Equinox (March 21), therefore Easter Sunday can fall in the period of 35 days between March 22 and April 25. In Ukraine Easter falls on a Sunday between April 4 and May 8.
The Eastern Church, which consists of the Orthodox churches, the Oriental churches and the Eastern-rite Catholic churches that are part of the Roman Catholic Church, such as the Ukrainian Catholic Church, follow the Julian Calendar (dates of Easter) ,and occasionally have Easter on the same day as the Western Church, which includes Roman Catholics, Lutherans and Anglicans, who follow the Gregorian Calendar (dates of Easter). However, because of the different methods of calculation Easter is usually celebrated anywhere from one to five weeks later in Ukraine. That is because of a combination of factors: the Julian Calendar lags thirteen days behind the Gregorian Calendar and there is a practice that Easter may not be celebrated before or on the same day as Jewish Passover.
In Ukraine Easter celebration as a Christian Holiday started in 988 A.D. when Kiyivan Rus' was baptized.
Easter celebration in Ukraine, as well as in other European cultures has a historical combination of Pagan and Christian traditions and rituals.
The English word "Easter" , as well as Easter Bunny symbol have derived from pre-Christian times.
In most Slavic languages, the name for Easter is either "Great Day" or "Great Night". In Ukraine the name for Easter is "The Great Day" (Velykden'), and there are several legends around the history of this name, including those which date back to Pre-Christian times.
Many of the seasonal traditions, rituals and symbols, such as: Easter Bread (Paska), painted eggs (pysanky) and color eggs (krashanky), pussy-willow, burning fires, games, group dances, songs, dousing with water were adopted from Pagan times and became a part of Christian Holidays. This explains the richness of Ukrainian culture today.
