Online Age Calculator
Calculate age in years (and optionally months/days) from birth date to today.
Frequently Asked Questions
- What date format?
- Use YYYY-MM-DD (e.g. 1990-05-15). The result is age as of today.
- Can I calculate age as of another date?
- This version uses today's date. For a specific 'as of' date, use a date calculator to get the difference.
- How are years calculated?
- Full years from birth date to today; if today's month/day is before birth month/day, one year is subtracted.
