Background

Inclusive vs. Exclusive Counting

Select a start and end date to instantly see the number of days in that period. You can choose to include the end date for an inclusive range.

  • By default, this tool calculates the number of full 24-hour periods between the start and end dates, which excludes the end date itself.
  • The 'include end date' option is useful for planning. An event from Monday to Friday is 5 days long with this option selected.
