Years, months and days calculated from full dates with leap-year and month-length handling.
Age Calculator | Exact Gregorian & Hijri Age
Calculate your exact age in Gregorian and Hijri calendars and see years, months, days, hours, minutes and seconds, together with useful birth-date details.
Age Calculator
Your age by Gregorian date
Note: A Hijri year is about 11 days shorter than a Gregorian year, so your Hijri age may appear higher. Years and months are counted differently between the two calendars, and Hijri calculations on this site use the Umm al-Qura calendar.
Gregorian age calculator
The Gregorian Age Calculator lets you calculate age accurately from a complete date of birth including day, month and year. Your Gregorian age is calculated up to today and displayed clearly in years, months and days.
The calculator uses the actual birth date rather than the birth year alone. It accounts for different month lengths, leap years, and whether your birthday has already occurred in the current year, making the result more precise than an approximate age calculation.
It also helps you see how old you are in the Gregorian calendar and the time elapsed since your birth date. For more details, use the dedicated Gregorian Age Calculator page.
Hijri age calculator
The Hijri Age Calculator calculates age from a complete Hijri birth date including day, month and year, while also showing the corresponding Gregorian date.
Hijri conversions on the site use Umm al-Qura, providing a consistent way to convert a birth date from Hijri to Gregorian or the other way around, especially for users in Saudi Arabia.
Hijri age and Gregorian age differ for the same person because the two calendars use years of different lengths. A Hijri year is shorter, so the number of completed Hijri years is slightly higher in most cases.
For the full Hijri result and the corresponding date, use the dedicated Hijri Age Calculator page.
Hijri calculations use Umm al-Qura. A date may differ by one day from other Hijri calendars or local moon-sighting practices.
How exact age is calculated
An age calculator should account for the full date of birth. This tool counts completed years first, then months and remaining days, while handling February, leap years and different month lengths correctly.
Use the main calculator for Gregorian age or Hijri age, and move to a focused tool when you need age on a specific date or the age difference between two people.
If you want to know exactly how long remains until your next birthday, the dedicated birthday countdown provides a separate live timer. Keeping each task focused makes the result easier to read and verify.
Why do age calculators sometimes show different results?
Different results can come from calendar rules, month lengths or the Hijri conversion method.
Leap years and month lengths: February may contain 28 or 29 days, while other months have 30 or 31 days. A precise calculator must handle those differences around month boundaries and birthdays.
Gregorian, Hijri and Umm al-Qura: Hijri years are shorter, and some Hijri conversion systems can differ by a day. This site uses Umm al-Qura and clearly notes that choice when Hijri dates are involved.

Use the age on a specific date tool, enter your birth date, then choose January 1, 2030 as the target date.
