How to use the Date Calculator

The first calculator counts calendar days, weeks, months and business days (Monday to Friday) between two dates. The second finds the date that is a number of days, weeks, months, years or business days before or after another date: handy for deadlines, notice periods, due dates and visa stays.

Frequently asked questions

Are public holidays excluded from business days?

No, only weekends are skipped, since holidays differ by country.

Should I include the end date?

Include it when both the first and last day count, for example hotel nights don't but a 5-day event from Monday to Friday does.
