Dormition of the Mother of God
While the Western Catholics celebrate the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Mother of God, and may do so on August 28, if they follow the Julian calendar. The Eastern Orthodox also celebrate it as the Dormition of the Mother of God, one of their 12 Great Feasts. The Armenian Apostolic Church celebrates the Feast of Dormition not on a fixed date, but on the Sunday nearest August 15. Moreover, the practices apart from doctrinal differences also vary, e.g. for the Eastern Orthodox the feast is preceded by the 14-day Dormition Fast.
