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.
