Age Calculator

How old are you exactly, in years, months and days?

A school application asks for a child's age in years and months, a job posting sets an age limit on a given date, a youth sports league sorts players by birth date. In every case, "about 30" is not good enough. Jood's age calculator gives your exact age in years, months and days, today or on any date you pick, in both the Gregorian and the Hijri calendar.

How to use it

1. Pick the "Date of birth". If your papers give a Hijri date, open "More options", choose "Hijri (Umm al-Qura)", then enter the day, month and year.
2. Leave "Calculate the age on" set to today, or change it to any other date, past or future.
3. The result appears at once and updates with every change, with no button to press.

What the result shows

• Your age in years, months and days, then in other units: total months, weeks, days and hours.
• The weekday you were born, and your next birthday: its date, how long until it and the age you turn.
• Your Hijri date of birth and your age in Hijri years, on the Umm al-Qura calendar, which can differ by one day from the month start set by moon sighting in your country.
• An age limit check: open "More options" and type the limit in "Age limit (optional)", say 45, and the tool tells you whether it is reached on the chosen date and the exact day it will be.

The "Copy result" button copies all of it as text, ready to paste into a message or a form.

Why it beats mental math

Subtracting the years is not enough if your birthday has not come round yet. And months differ in length: February has 28 or 29 days, the others 30 or 31. The tool works on the real calendar. For someone born on February 29, the birthday is counted on February 28 in common years, and the tool notes that some bodies use March 1 instead.

Other uses

• Length of service: enter your hire date instead of a birth date.
• Time between two dates: how long a lease has run, or the gap between two documents.
• A baby's age: pediatricians count in months for two years, and the total in months is shown directly.

Your dates stay with you

The whole calculation runs in your browser, so the date of birth is never sent to our server. To turn a duration into other units, use the time converter.
