Therefore, Easter is observed anywhere between March 22 and April 25 every year. Orthodox Christians use the Julian calendar to calculate when Easter will occur and typically celebrate the holiday a week or two after the Western churches, which follow the Gregorian calendar.
The exact origins of this religious feast day’s name are unknown. Some sources claim the word Easter is derived from Eostre, a Teutonic goddess of spring and fertility. Other accounts trace Easter to the Latin term hebdomada alba, or white week, an ancient reference to Easter week and the white clothing donned by people who were baptized during that time.
Through a translation error, the term later appeared as esostarum in Old High German, which eventually became Easter in English. In Spanish, Easter is known as Pascua; in French, Paques. These words are derived from the Greek and Latin Pascha or Pasch, for Passover. Jesus’ crucifixion and resurrection occurred after he went to Jerusalem to celebrate Passover (or Pesach in Hebrew), the Jewish festival commemorating the ancient Israelites’ exodus from slavery in Egypt. Pascha eventually came to mean Easter.
The day before Lent, known as Mardi Gras or Fat Tuesday, is a last hurrah of food and fun before the fasting begins. The week preceding Easter is called Holy Week and includes Maundy Thursday, which commemorates Jesus’ last supper with his disciples; Good Friday, which honors the day of his crucifixion; and Holy Saturday, which focuses on the transition between the crucifixion and resurrection. The 50-day period following Easter Sunday is called Eastertide and includes a celebration of Jesus’ ascension into heaven.
In the Orthodox and Eastern Catholic Churches, Easter eggs are dyed red to represent the blood of Christ, shed on the Cross, and the hard shell of the egg symbolized the sealed Tomb of Christ — the cracking of which symbolized his resurrection from the dead. Easter eggs are blessed by the priest at the end of the Paschal Vigil (which is equivalent to Holy Saturday), and distributed to the faithful. The egg is seen by followers of Christianity as a symbol of resurrection: while being dormant it contains a new life sealed within it.
HAPPY EASTER FILLED WITH PEACE AND LOVE TO YOU ALL !
