Coptic to Hijri (Islamic) Date Converter

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

1. 1

   Step 1

   Enter the complete Coptic date — day, month, and year.

2. 2

   Step 2

   We apply both systems' rules: a Coptic year runs about 365 days against the Hijri (Islamic) 354 (≈11 days apart each year).

3. 3

   Step 3

   The result shows the correct Hijri (Islamic) day, with Hijri (Islamic) leap years applied date by date.

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

• 2

  Enter the Coptic–Hijri (Islamic) dates in YYYY-MM-DD format to avoid ambiguity — some conventions read 03/04 as March fourth and others as April third, and a swapped month and day silently shifts every result this page derives.

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

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

• Reversing the direction is a silent trap: converting from the Hijri (Islamic) calendar back to the Coptic 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.
