Days

Calculates the difference in whole days between the two dates using the Gregorian calendar.

Use cases

  • Calculating how many days are left until an event.
  • Calculating the duration of a project or contract.
  • Checking how many days have passed since a date.

How it works

  1. 1

    Pick the start date

    Select the first day.

  2. 2

    Pick the end date

    Select the second day and get the days between them.

Technical details

  • Example: from March 1 to March 31 there are 30 days. If you want to count both ends (for example, days of a trip), add 1: that makes 31.
  • The order of the dates doesn't matter: the result is always positive.
  • It counts calendar days, weekends and public holidays included. It doesn't calculate business days.
  • Daylight saving changes don't affect the result: calendar days are compared, not hours.

Frequently asked questions
