Knowing your exact age in years, months and days is handy for official forms, tracking a child’s growth or simple curiosity. Enter your date of birth in Gregorian or Hijri (Umm al-Qura) and this calculator shows your exact age, plus totals in months, weeks and days and the date of your next birthday.
How to use
- Choose the calendar: Gregorian or Hijri.
- Enter your date of birth (for Hijri, pick the year, month and day).
- Optionally change the “until date” to compute your age on any other day — it defaults to today.
- The result appears instantly: years, months and days, with extra details in the table.
Frequently asked questions
How is the exact age calculated?
The difference between your birth date and the target date is computed in calendar years, months and days, borrowing the correct number of days from the preceding month when needed.
Can I calculate my age from a Hijri birth date?
Yes. Switch to Hijri mode and enter your Hijri year, month and day of birth. The tool converts it to Gregorian using the Umm al-Qura calendar, then computes the age.
Why do I get an error for the 30th of some Hijri months?
Some Hijri months are only 29 days long, so the 30th does not exist for those months in the Umm al-Qura calendar and the tool shows an error.
How is my next birthday determined?
Your birth day and month are applied to the current year; if that date has passed (or is today), the following year is used. Leap years are handled for February 29 birthdays.
