Age Calculator
Calculate age from a birth date to today or another date.
The count uses calendar dates, not the time of day.
How to calculate age
1. Choose the birth date.
2. Leave As of empty for today, or pick another date.
3. Read the years, months, and days.
How the years and months are counted
A year is counted when the anniversary month and day have arrived. A month is counted from the day of the month. If that day has not arrived yet, the month is not complete. The time of birth is ignored.
