Islamic Age Calculator
See your completed age in Gregorian solar years and Hijri lunar years, and convert your birth date to its calculated Hijri equivalent.
Hijri age uses Umm al-Qura calendar dates. Lunar years are shorter than Gregorian solar years, so the two ages can differ. Your birth date is processed entirely in your browser and is not sent to our server.
Why is Hijri age different?
A Hijri year follows the lunar calendar and is roughly 354 or 355 days long, while a Gregorian year follows the solar calendar and is roughly 365 days long. Because each Hijri year is shorter, your completed Hijri age gradually becomes higher than your completed Gregorian age.
How is the Hijri birth date calculated?
Your Gregorian birth date is converted using the Umm al-Qura calendar available through the browser. The calculation happens locally on your device. We do not send your birth date to an external conversion service.
Can the Hijri birthday differ by one day?
It can. Calculated Hijri calendars are useful references, but historical or locally observed Islamic dates can vary depending on moon sighting and the authority followed.
