How to use this tool

  1. Select the start and end dates.
  2. Calculate the calendar-day difference.
  3. To count both endpoints, add one to a nonnegative difference.

An example you can verify

Count calendar days between two deliveries or dates.

Example input

Start: 2026-03-28
End: 2026-03-30

Expected result

2 days.

No extra day is added for counting both endpoints and holidays are not excluded. Calculation avoids daylight-saving effects.

Settings and limits

The start date is subtracted from the end date. No extra day is added to count both endpoints. Dates use UTC to avoid daylight-saving changes.

Frequently asked questions

Does daylight saving affect the result?

No. Calendar dates are compared at midnight UTC. An earlier end date produces a negative number.
