Gregorian → Hijri

Select a date

Hijri → Gregorian

Enter a Hijri date

Uses the Umm al-Qurā calendar. The start of each Islamic month depends on the local moon sighting, so the exact day can differ by ±1.

How the Hijri calendar works

The Islamic calendar is lunar: 12 months of 29–30 days, about 354 days a year — roughly 11 days shorter than the Gregorian year, which is why Islamic dates shift earlier each year. This matters for Zakat, which is due after one full lunar year (hawl).

Gregorian to Hijri, and Hijri to Gregorian

Enter a Gregorian date to see the Hijri equivalent, or a Hijri date (day, month, year AH) to see the Gregorian date. See today’s Islamic date and the Ramadan & Eid countdown.

Guidance only, not a fatwa. Rulings vary by madhhab; confirm with a qualified scholar.

Frequently asked questions

How do I convert a Hijri date to Gregorian?

Enter the Hijri day, month and year (AH) in the converter above and it returns the Gregorian date using the Umm al-Qurā calendar.

Is the converted date exact?

It follows the Umm al-Qurā calendar; because months begin on the local moon sighting, the actual day can differ by ±1.

Why does the Islamic year shift?

The lunar year is ~354 days, about 11 days shorter than the solar year, so Hijri dates move earlier on the Gregorian calendar each year.
