ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

Convert a date between the Gregorian (Western) calendar and the Islamic Hijri calendar in either direction. 17 September 2026 in the Gregorian calendar corresponds to roughly 5 Rabi al-Thani 1448 AH in the Hijri calendar — since the Islamic calendar is lunar and about 11 days shorter than the solar year, the gap between the two calendars shifts slightly every year.

Hijri Calendar Converter FAQs

How accurate is the Hijri date shown?
It uses standard calendar conversion calculations — actual moon-sighting-based dates can occasionally differ by a day depending on your region and local sighting announcements.
Does it convert both ways?
Yes, convert a Gregorian date to Hijri, or a Hijri date back to Gregorian.
Why might my local Hijri date differ by a day?
The Islamic calendar depends on moon-sighting, which varies by country/region — the calculated date here is a standard astronomical approximation, not a religious ruling.
Can I use this to find upcoming Islamic dates like Ramadan or Eid?
Yes — convert the expected Gregorian date to Hijri to check alignment, though official dates are still confirmed by moon-sighting announcements closer to the time.
