Hijri (Islamic) to Julian Date Converter

Enter a date in the Hijri (Islamic) calendar and the tool returns the equivalent date in the Julian 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 Julian 365 (≈11 days apart each year).

3. 3

   Step 3

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

• 1

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

• 2

  Watch century boundaries and very old dates in the Hijri (Islamic)–Julian 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

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

• Anniversaries do not survive conversion unchanged: a Hijri (Islamic) date maps to a fixed Julian date, but next year's Hijri (Islamic) anniversary lands on a different Julian date. Reconvert each occurrence instead of adding one year to the last result.

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