FAQs

How do I know the current Coptic year?

Subtract 283 or 284 from the Gregorian year depending on the month. Before September subtract 284, after subtract 283.

Why is month 13 short?

Month 13 (Nasie/Epagomenal) contains extra days to complete the solar year: 5 days in regular years, 6 in leap years.

How accurate is the conversion?

The conversion is very accurate since both calendars are solar. The difference with Julian calendar is fixed.
