Hijri Age Calculator
Enter a birth date to get today’s date in both the Gregorian and Hijri (Umm al-Qura) calendars, the birth date converted to Hijri, and the exact age in years, months and days in both calendars — computed in your browser.
About this tool
The conversion uses the Umm al-Qura calendar through your browser’s own Intl API — no server does the math, so it works offline and nothing is sent anywhere.
A Hijri year is about 11 days shorter than a Gregorian year, so a person’s Hijri age gains roughly one extra year every 33 years. Both figures are shown side by side.
Hijri Age Calculator — FAQ
Why is the Hijri age larger than the Gregorian age?
The Hijri year is about 354 days versus 365 for the Gregorian year, so more Hijri years fit into the same lifetime.
Which Hijri calendar is used?
Umm al-Qura via your browser’s Intl API — the official calendar of Saudi Arabia. Other countries may differ by a day at month boundaries.
Is it valid for official documents?
For quick reference, yes. For official documents, rely on the issuing authority’s own conversion.
