An exact age calculator computes your precise age in years, months, days, hours, and even seconds from your date of birth to the current moment. This is more complex than it appears because months vary in length (28–31 days) and leap years add an extra day every 4 years.

- 1Start with today's date minus birth date
- 2If day of month < birth day, borrow from the previous month and subtract 1 month
- 3If month < birth month after adjustment, borrow from the year and subtract 1 year
- 4Convert total days to hours, minutes, and seconds for the precise figure
