Hijri (Islamic) to Gregorian Date

Enter a date in the Hijri (Islamic) calendar and the tool returns the equivalent date in the Gregorian 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 apply both systems' rules: a Hijri (Islamic) year runs about 354 days against the Gregorian 365 (≈11 days apart each year).

3. 3

   Step 3

   The result shows the correct Gregorian day, with Gregorian leap years applied date by date.

• 1

  Hijri (Islamic) and Gregorian 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 Gregorian equivalent instead of shifting the year by a fixed offset.

• 2

  Watch century boundaries and very old dates in the Hijri (Islamic)–Gregorian system: historical calendars dropped or added days when they were adopted, which is invisible in daily use but material for long-range historical calculations here.

• 3

  Enter the Hijri (Islamic)–Gregorian 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.

• Reversing the direction is a silent trap: converting from the Gregorian 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.

• Epoch offsets are pair-specific: day zero of Hijri (Islamic) and of Gregorian are different dates, and constants borrowed from another calendar pair are silently wrong by days or years. Use the Hijri (Islamic) → Gregorian relation itself, not a remembered number.
