How to use it
Choose your date of birth and press Calculate. The calculator compares it to today's date and reports your age in years, months, and days.
How it's calculated
Subtract the birth year from the current year, then adjust down if your birthday hasn't occurred yet this year. The remaining months and days are counted to the current date.
Example
Example: Born 15 March 2000, on 4 September 2026 → 26 years, 5 months, and 20 days old.
