Beginning of the New Year, Synaxis of Theotokos. Mon Sep 1st
The origins of the Orthodox Churches’ New Year on September 1 can be traced to the First Ecumenical Council at Nicaea (325) establishing the liturgical calendar. September was historically significant for the Hebrews as the beginning of their year, associated with the harvest with thanksgiving offering to God (Exodus 23). Also according to Holy Tradition, Jesus Christ entered the synagogue in Nazareth to read from the scroll of Isaiah, while proclaiming an "acceptable year of the Lord" (Luke 4).
