Frequently Asked Questions

Does the calculator include or exclude the end date?
By default, the calculator counts up to but not including the end date, which matches the standard convention for "days until." You can toggle this to include the end date if needed.
Are public holidays excluded from the workday count?
The business day count excludes Saturdays and Sundays. Public holidays vary by region and are not automatically excluded, but you can manually subtract known holidays from the workday total.
Can I calculate days since a past date?
Yes. Simply enter a past date as the "end" date or swap the dates. The calculator handles both past and future date differences.
