Frequently asked questions
Does the calculator include the end date?
By default it measures elapsed days and excludes the end date. Turn on “Include end date” when both calendar dates should count.
How are business days counted?
Business days include Monday through Friday and exclude Saturdays and Sundays. Public holidays are not excluded because they vary by country.
Are leap years handled correctly?
Yes. CountDays uses real calendar dates, including February 29 in leap years and the correct length of every month.
Do you store my dates?
No. Every calculation runs locally in your browser. CountDays does not require an account or send your entered dates to a database.
