The liturgical calendar used by the Coptic Orthodox Church of Alexandria and other churches in the Coptic Orthodox tradition reckons dates based on the Alexandrian calendar. It observes twelve 30-day months, followed by a five or six-day intercalary period known as the “Little Month.” This system results in unique dates for major feasts, including Easter, which are often distinct from those calculated using the Gregorian calendar.
This specific calendrical system maintains a continuous link to the rich history and traditions of early Christianity in Egypt. Its structure, dating back to Pharaonic times, underscores a deep connection to the cultural heritage of the region. The observance of its distinct liturgical year allows Coptic Christians to commemorate key figures and events in their religious history, reinforcing their spiritual identity and communal bonds. The continued use of this ancient system demonstrates a remarkable example of cultural preservation and religious continuity.
