Christian feast day: Pachomius the Great

Pachomius, also known as Saint Pachomius the Great, is generally recognized as the founder of Christian cenobitic monasticism. Coptic churches celebrate his feast day on 9 May, and Eastern Orthodox and Catholic churches mark his feast on 15 May or 28 May. In Lutheranism, he is remembered as a renewer of the church, along with his contemporary, Anthony of Egypt on 17 January.
