What is an age calculator?
An age calculator computes your exact age in years, months, and days from your date of birth. It also shows your next birthday countdown, the day you were born, and checks eligibility for age-based benefits.
Formula used
Age = Difference between Date of Birth and today (or any target date)
Algorithm:
1. Subtract birth year from current year
2. If birthday hasn't occurred yet this year → subtract 1
3. Calculate remaining months and days separately
How to use this calculator
- Enter your date of birth
- The 'As of' date defaults to today — change to check age on any past or future date
- Click Calculate — see exact years, months, days, and next birthday countdown
Example
Example 1 — Exact age:
