Frequently Asked Questions

How are business days calculated?

Business days are weekdays (Monday through Friday). This calculator counts all weekdays between the two dates, not accounting for public holidays which vary by country.

Why would I need the date difference?

Date difference calculations are useful for project deadlines, contract durations, anniversary countdowns, age verification, subscription periods, and travel planning.

Does the calculator include the end date?

The calculator counts the days between the two dates exclusively (not counting the start date or the end date itself). To include the end date, add 1 to the result.
