To this day, traditional Orthodox Christians will use the Byzantine calculation of the World Era in conjunction with the Anno Domini (AD) year. Both dates appear on Orthodox cornerstones, ecclesiastical calendars and formal documents. The ecclesiastical new year is still observed on September 1 (or on the Gregorian Calendar's September 14 for those churches which follow the Julian Calendar). September 2022 marked the beginning of the year 7531 of this era.
