Age Calculator: Find Your Exact Age in Years, Months & Days

An age calculator tells you your exact age from your date of birth — not just in years, but in years, months and days. It is useful for forms, eligibility checks, and just out of curiosity.

How is exact age calculated?

The calculator compares your date of birth with a chosen date (today by default). It counts complete years, then the remaining months, then the remaining days — adjusting for different month lengths and leap years.

What else can it show?

• Total age in months, weeks and days.
• How many days are left until your next birthday.
• Age on any future or past date (useful for exam or job eligibility).

Example

If you were born on 15 May 1990 and check on 8 June 2026, your age is 36 years, 0 months and 24 days — which is about 13,173 days.
