The calendar of the Ethiopian church came from Egypt and as to methods and dates agrees with the calendar of the Coptic Church. But the two calendars differ with regard to the saints’ days and the time of observing them. The year of the Ethiopian calendar contains 365 days to which is added every fourth year an extra day. Each year in this four-year period is dedicated to one of the four Evangelists who come in the following order: Mathew, Mark, Luke and John. The year of Luke is the Ethiopian Leap year and is the year which precedes the western leap year.
