Annunciation of the Lord in Greece falls on March 25th each day and celebrates the announcement by the angel Gabriel to the Virgin Mary that she would conceive Jesus the Son of God.
People can attend church in honor of the visit by the Angel Gabriel to the Virgin Mary with the Annunciation. Many Christians will enjoy a "Feast of the Annunciation" by celebrating a feast.
Luke 1:26 states that the Annunciation occurred in the sixth month of Elizabeth's pregnancy with John the Baptist. The date of March 25 is a close approximation to the vernal equinox which is nine months before Christmas.
