Learn the 13 Coptic months and how they map to Gregorian dates.
Inputs
How the Coptic Calendar Works
The Coptic year has 13 months: 12 months of 30 days plus a small epagomenal month of 5 or 6 days in leap years.
Leap Year Rule
A leap day is added every four years without exception, so the Coptic New Year usually falls on 11 September (or 12 September before a Gregorian leap year).
Accuracy Note
The Coptic calendar uses a fixed solar year similar to the Julian calendar; long-term drift versus the Gregorian calendar is about 1 day every 3322 years.
