Calculate Duration Between Dates

The number of days between two dates is calculated by finding the difference between the start date and end date. This date duration calculator can calculate the exact number of days and can also exclude weekends, selected weekdays, and specific dates.

Enter the start date and end date in the date duration calculator and click Calculate Duration. The calculator determines the date difference and can optionally include the end date or exclude selected weekdays and custom dates.

An inclusive date calculation counts both the start and end dates when applicable. An exclusive calculation does not count the end date. This calculator lets you choose whether the end date should be included in the result.

Working days are the days that remain after excluding weekends or other selected weekdays. Use this calculator to exclude Saturday, Sunday, or any other weekday and calculate the number of counted days between two dates.
