Age calculator
Pick a date of birth and see the exact age in years, months and days, how long until the next birthday, the weekday of birth, and the Hijri birth date and age.
Leave it on today, or pick another date, for example the closing date of a form that asks your age.
Runs on your phone. Nothing you pick is uploaded or saved.
How it is counted
The calculator counts how many whole calendar months fit between the two dates, then the days left over. Twelve months make a year.
If you were born on the 31st, a month "ends" on the last day of a shorter month. Born on 29 February? Outside leap years your birthday is counted on 28 February.
A Hijri year has 354 or 355 days, about 11 days fewer than a Gregorian year. So every 33 years or so, your Hijri age moves one year ahead.
Hijri dates here use the Umm al-Qura calendar built into your browser. Official dates in the UAE depend on sighting the new moon, so a date can be one day off.
Sources: Gregorian calendar rules (leap years every 4 years, except century years not divisible by 400). Hijri dates use the Umm al-Qura calendar as built into your browser through the Unicode CLDR and ICU calendar data (calendar "islamic-umalqura"); if your browser lacks it, a standard tabular Islamic calendar is used and can be a day or two off. The Hijri year has 12 lunar months of 29 or 30 days, 354 or 355 days in total. In the UAE, the start of Ramadan, Shawwal and Dhu al-Hijjah is set by moon sighting, so official dates can differ by a day. This is a calculator, not an official record: for documents, use the date on your official papers.
