About the Coptic calendar

The Coptic calendar, used by the Coptic Orthodox Church and by Egyptian farmers, descends from the ancient Egyptian civil calendar with the leap day that the Decree of Canopus proposed in 238 BCE and Augustus enforced. It has twelve months of 30 days and a short month, Nasie, of five or six. Years count from the Era of the Martyrs, beginning in 284 CE when Diocletian became emperor, and the year begins at Nayrouz, 11 or 12 September.
