Date difference and age calculator

Find the time between two dates, or enter a date of birth to get an exact age.

Fill in the fields to see the result.

How it works

Whole calendar months are counted first, then the remaining days. A month from the 31st ends on the last day of a shorter month, and a February 29 birthday falls on February 28 in other years.

Weekdays count Monday to Friday and ignore public holidays.
