About the Age Calculator (Hijri & Gregorian)
The Islamic (Hijri) calendar is lunar, so it runs about 11 days shorter than the Gregorian year. That means your age in Hijri years is a little higher than your Gregorian age, and Islamic dates drift earlier each year against the Western calendar.
This Age Calculator shows your exact age in both the Hijri and Gregorian calendars, converts any date between the two, and tells you when your next Hijri birthday falls — all calculated privately in your browser.

How the Age Calculator (Hijri & Gregorian) works
These tools are built on established, transparent methods. Prayer times are calculated astronomically from the sun's position for your exact coordinates, using the angle conventions of well-known authorities — the Muslim World League, ISNA, Umm al-Qura (Makkah), the Egyptian General Authority and the University of Karachi — with a choice of Standard or Hanafi Asr. Hijri dates use the widely used tabular (arithmetic) Islamic calendar, and the inheritance calculator applies the fixed Quranic shares (Faraid) with residual (Asaba) distribution and proportional adjustment (Awl).
Everything runs in your browser, so your location and family details stay private.
Tips & best practices
- Your Hijri age is higher than your Gregorian age because the lunar year is about 11 days shorter.
- Hijri dates here use the tabular calendar, so an official moon-sighting date may differ by a day.
- Use it to convert important dates — a birth, a milestone — into their Islamic equivalent.
Standards & accuracy
Prayer times use the standard astronomical algorithm with recognised calculation methods (MWL, ISNA, Umm al-Qura, Egypt, Karachi); Hijri dates use the tabular Islamic calendar; inheritance follows the core rules of Faraid.
Prayer times are calculated astronomically and may differ from your local mosque by a few minutes; for Fajr and Isha at high latitudes, methods vary — follow your community. The start of Islamic months depends on the local moon sighting, so Hijri dates may differ by a day from a sighting-based calendar. The inheritance tool covers the most common heirs for education and planning — always confirm a real distribution with a qualified scholar.
