Find out your exact age in years, months, and days with our Age Calculator. Enter your date of birth and the tool instantly shows your precise age the same way official documents count it — complete years first, then months, then days.

The calculator also shows your total age in days, weeks, and months, which is handy for milestone tracking (like celebrating 10,000 days) or filling in forms that ask for age in months.

Leave the second date empty to calculate your age as of today, or pick any date to see how old you were on a past date or how old you will be on a future one. A next-birthday countdown is included, so you always know how many days remain until the candles come out.

Formulă
Age = complete years + remaining months + days between the two dates

Întrebări Frecvente

Age is calculated by counting complete calendar years first, then the remaining whole months, then the remaining days — the same way most official documents (passports, IDs) define age.
How do I calculate age from date of birth?
Enter your date of birth and leave the second field empty — the calculator uses today's date automatically. You can also pick any date to find how old you were (or will be) on that day.
How many days old am I?
The result panel shows your total age in days, weeks, and months — useful for milestone celebrations like 10,000 days old.
When is my next birthday?
The countdown shows how many days remain until your next birthday, based on the date entered in the first field.
