How many days are between two dates?

Subtract the start date from the end date. This tool counts whole days in UTC, so a result of 30 means exactly 30 × 24 hours, unaffected by daylight-saving changes.

What counts as a business day?

Business days are Monday through Friday. The count excludes weekends but not public holidays, which differ by country — subtract those manually if needed.

Does the order of dates matter?

No. The calculator returns the absolute span, so swapping the start and end dates gives the same number of days.
