How this age calculator works
Age is counted the way people talk about it: complete calendar years first, then complete calendar months, then the leftover days — respecting real month lengths and leap years. The birthday countdown uses the next occurrence of your birth date, including Feb 29 birthdays (celebrated Mar 1 on non-leap years).
Common uses
- Check your exact age for a form, visa, or registration deadline.
- Count down to a birthday or milestone (10,000 days!).
- Work out someone's age at a past or future date with the date calculator.
- Expecting? Estimate a delivery window with the pregnancy due date calculator.
