The Indiction — beginning of the Ecclesiastical New Year.
September 1 marks the Indiction, the beginning of the Ecclesiastical New Year. The custom derives from the civil calendar of the Roman Empire, in which the yearly cycle of taxation and public life began in September, and the Church took up this reckoning for her own cycle of feasts.
On this day the Church prays for God's blessing upon the new year, remembering that Christ read in the synagogue at Nazareth the words of Isaiah, "The Spirit of the Lord is upon me... to proclaim the acceptable year of the Lord." It is also kept in our time as a day of prayer for the protection of the natural environment.
Feast day
On the New Calendar, Beginning of the Church Year is commemorated on September 1. Churches on the Old (Julian) Calendar keep the feast on September 14 of the civil calendar.
