Frequently asked questions
Is the end date counted?
By default the answer is the distance between the dates, so Monday to Tuesday is 1 day. Turn on "Count the end date too" to include both days.
How are business days counted?
Every day in the range that is not a weekend day and not a holiday you chose. The weekend can be Saturday and Sunday, Sunday only, or Friday and Saturday.
How accurate is the holiday list?
It holds the national holidays of 2026 and 2027. Dates that depend on the moon can differ by a day, and state holidays are not included. Add your own dates for anything else.
Is anything uploaded?
No. The calculation runs in your browser and nothing you enter is sent to a server.
