The Dormition of the Mother of God is a Great Feast of the Eastern Orthodox, Oriental Orthodox, and Eastern Catholic Churches (except the East Syriac churches). It celebrates the "falling asleep" (death) of Mary the Theotokos ("Mother of God", literally translated as God-bearer), and her being taken up into heaven. The Feast of the Dormition is observed on August 15, which for the churches using the Julian calendar corresponds to August 28 on the Gregorian calendar. The Armenian Apostolic Church celebrates the Dormition not on a fixed date, but on the Sunday nearest 15 August. In Western Churches the corresponding feast is known as the Assumption of Mary, with the exception of the Scottish Episcopal Church, which has traditionally celebrated the Falling Asleep of the Blessed Virgin Mary on August 15.
Christian canonical scriptures do not record the death or Dormition of Mary. Hippolytus of Thebes, a 7th- or 8th-century author, writes in his partially preserved chronology of the New Testament that Mary lived for 11 years after the death of Jesus, dying in AD 41.
