12 June

12 June The Christians of Egypt placed their life-giving river, the Nile, under the archangel’s protection. They adopted the feast as kept by the Greeks and kept it on November 12. On the twelfth of each month they celebrate a special commemoration of St Michael, but on June 12, when the river starts to rise, they keep as a holiday of obligation the feast of St Michael “for the rising of the Nile”: euche eis ten symmetron anabasin ton potamion hydaton. http://www.wilsonsalmanac.com/michaelmas.html
