This feast, like that of the Assumption of Mary, originated in Jerusalem. It began in the fifth century as the feast of the basilica Sanctae Mariae ubi nata est, now the Basilica of Saint Anne. In the seventh century, the feast was celebrated by the Byzantines and at Rome as the feast of the Birth of the Blessed Virgin Mary. The feast is also celebrated by Syrian Christians on 8 September and by Coptic Christians on 1 Bashans (i.e., 9 May). The feast was included in the Tridentine Calendar for 8 September and has remained on that date.
