Frequently Asked Questions
Common questions about the free online business days calculator.
Enter the start and end dates. The tool walks the range one day at a time, skips weekends and
any holiday you list, and counts the rest.
The start date is always counted. Use the check box to decide whether the end date is
included, which is useful for delivery windows.
Type one holiday per line in the format YYYY-MM-DD. Commas and semicolons also work, and
lines that are not valid dates are ignored.

excluded as a weekend.

of days.
