📅 Days Between Dates Calculator

Count how many days there are between two dates, including business days and weekend days.

How to use it

Choose a start date and an end date. By default the end date is not counted (from Monday to Tuesday is 1 day). Tick "Include the end date" to count both days.

Business days

Business days count Monday to Friday only. Public holidays are not removed, because they change from country to country — subtract them yourself if needed.

Uses

  • Deadlines, contracts and notice periods.
  • Pregnancy and project countdowns.
  • Planning trips and vacations.
