Hijri (Islamic) to Coptic Date Converter

Enter a date in the Hijri (Islamic) calendar and the tool returns the equivalent date in the Coptic calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Hijri (Islamic) date — day, month, and year.

2. 2

   Step 2

   We anchor each system's epoch, then convert day by day — Hijri (Islamic): epoch 622 CE (2026 CE ≈ AH 1447–1448); Coptic: the Coptic year ≈ 2026 − 284 (it begins ≈ 11 September).

3. 3

   Step 3

   Read the exact Coptic date: a year spanning 365–366 days, counted month by month.

  Hijri (Islamic) and Coptic dates do not map one-to-one — the two systems start from different epochs and count leap years differently, so enter the full Hijri (Islamic) date and read the Coptic equivalent instead of shifting the year by a fixed offset.

  Time zones can move a Hijri (Islamic)–Coptic date by a full day around midnight: today in one zone is still yesterday or tomorrow in another, so anchor the calculation to the zone your event actually follows before you enter anything.

  Before a Hijri (Islamic)–Coptic date goes into a booking or a flight, re-enter it in a second tool as a cross-check — pages like Hijri (Islamic) to Coptic Date Converter apply fixed rules and cannot warn about a transposed input digit.

• Reversing the direction is a silent trap: converting from the Coptic calendar back to the Hijri (Islamic) calendar needs the inverse relation, and off-by-one errors cluster at month boundaries where the systems disagree. Verify the round trip returns your original date.

• The Hijri (Islamic) and Coptic calendars differ in year length and leap pattern, so a fixed-day offset — 365, 354, any memorized constant — drifts the Coptic date badly. Convert the complete date so both leap rules apply.
