The Annunciation, also referred to as the Annunciation to the Blessed Virgin Mary, is the Christian celebration of the announcement by the angel Gabriel to the Virgin Mary that she would conceive and become the mother of Jesus, the Son of God.

It is celebrated on March 25th, exactly 9 months before Christmas. But this year because that traditional date for the Annunciation fell on Good Friday, the feast was moved to today.
