The 2025 Orthodox Calendar: A Comprehensive Guide

The Orthodox Christian calendar, unlike the Gregorian calendar used in most of the world, follows a Julian calendar system with adjustments for Easter and other movable feasts. This creates a unique and fascinating liturgical year, rich in tradition and meaning. Understanding the 2025 Orthodox calendar requires an appreciation of its complexities and the theological principles that underpin it. This comprehensive guide aims to illuminate the key dates, feasts, and observances for the year 2025 within the Orthodox Christian tradition.

The Julian Calendar and its Implications:

The Orthodox Church predominantly uses the Julian calendar, which is 13 days behind the Gregorian calendar. This difference has significant implications for the dating of fixed feasts. For example, Christmas, a fixed feast celebrated on December 25th in the Gregorian calendar, falls on January 7th in the Julian calendar. This discrepancy is a crucial point to remember when comparing Orthodox and Gregorian calendars.

Movable Feasts and the Calculation of Easter:

The most significant difference lies in the calculation of Easter. The Orthodox Church uses a different calculation method than the Gregorian calendar, resulting in a different date for Easter each year. This calculation is based on the lunar cycle and astronomical observations, a system that has been used for centuries. The date of Easter determines the timing of many other movable feasts, such as Ascension, Pentecost, and the various Sundays of Great Lent. For 2025, the date of Orthodox Easter is April 27th.
