The Feast of the Annunciation to the Most Holy Theotokos is celebrated on one day March 25, exactly nine months before the Nativity of Christ. There is one day of Prefeast (March 24), followed by the Feast itself. On March 26, we celebrate the Synaxis of the Archangel Gabriel.

Because the Feast of the Annunciation falls during Great Lent, there is no Postfeast of the Feast.
