Age from date of birth is calculated by measuring the actual elapsed time between the birth date and today, while accounting for the number of days in each month, leap years, and whether the annual birthday has already occurred in the current year.
This allows the age calculator to show your actual calendar age more precisely instead of displaying completed years only.

Frequently asked questions about Gregorian age
How old am I in the Gregorian calendar?
Enter your day, month and year of birth. The calculator compares that date with today and calculates your current Gregorian age automatically.
How is age calculated from a date of birth?
Age is calculated from the elapsed calendar time between the date of birth and today, using actual month lengths and leap-year rules.
Is the age calculator accurate?
The result is based on the date you enter, so make sure the day, month and year are correct before calculating.
What is the difference between Gregorian and Hijri age?
Gregorian age uses the Gregorian solar calendar, while Hijri age uses a lunar calendar with a shorter year. For the same person, the number of completed Hijri years is usually higher.
Does the calculated age change every day?
Yes. Exact age in years, months and days depends on today’s date, so the remaining day count can change daily until another month or year is completed.
