The Feast of the Annunciation is traditionally celebrated on March 25. This date is chosen because it falls exactly nine months before Christmas, representing the approximate duration of human gestation between the announcement of the Incarnation and the birth of Jesus.12
In the Roman Catholic Church, the feast may be transferred to another date if March 25 coincides with a Sunday of Lent, Holy Week, or the Easter Octave. It is not considered a holy day of obligation. Known also as Lady Day, the feast commemorates the Virgin Mary's willing consent to the message delivered by the angel Gabriel.12
