Age calculator
More than a simple “How old am I?” answer
An exact age calculator should not simply subtract your birth year from the current year. It compares complete calendar dates, respects different month lengths and leap years, and returns completed years, months and remaining days.
You can calculate Gregorian age or Hijri age from the same tool. Hijri conversion uses the Umm al-Qura calendar, and both calendar ages are shown separately so the result is easy to understand.

Two calendar systems
Gregorian age and Hijri age
Gregorian Age Calculator
A Gregorian year has 365 days, or 366 in a leap year. Exact age therefore requires complete date comparison, not simple year subtraction.
Open Gregorian calculatorHijri Age Calculator
A Hijri year is shorter than a Gregorian year, so the numerical Hijri age can be higher. Hijri conversion on this site uses Umm al-Qura.
Open Hijri calculatorHijri calendar note: Umm al-Qura is the reference used here. Some Hijri calendars or local moon-sighting practices may differ by one day.

Transparent calculation
Why can two age calculators show different results?
Differences can come from leap-year handling, timezone assumptions or the Hijri calendar system used. Some sites divide elapsed days by 365, which is only an approximation. This site compares real calendar dates, keeps Gregorian and Hijri age separate, and states that Umm al-Qura is used for Hijri conversion.
