What the date difference means

The calculator subtracts the earlier date from the later date and reports the number of 24-hour calendar intervals between them. For example, January 1 to January 2 is one day.

Inclusive versus exclusive counting

This result uses exclusive counting: it does not count both boundary dates as full days. If you need to count every named date in a period—for example, every day of a trip including arrival and departure—add one to the result.

Calendar days and business days

The tool counts all calendar days, including weekends and holidays. Business-day calculations depend on the working week and local holiday calendar, so they require a different method.
