How do you calculate the time between two dates?
Subtract the earlier date from the later date. Our calculator breaks the result into years, months, weeks, days, hours, minutes, and seconds, plus working days (weekdays only).
Does the calculation include both the start and end dates?
The start date is included and the end date is excluded. For example, January 1 to January 2 equals 1 day.
How are working days calculated?
Working days count only weekdays (Monday through Friday), excluding Saturdays and Sundays. Public holidays are not excluded from the count.
Does the calculator account for leap years?
Yes. Leap years are fully accounted for — February has 29 days in leap years.
