Workday calculator
Business Days Calculator
Count weekdays between two dates and optionally exclude listed U.S. federal holidays for planning deadlines.
Enter two dates and run the calculator.
Formula
The calculator walks through the date range, removes Saturdays and Sundays, then removes listed U.S. federal holidays when the holiday option is enabled. The start and end dates can be included or excluded.
This is a general calendar planning tool. It does not determine legal, payroll, tax, or contract obligations.

Should I include the start date?
For elapsed time, many users exclude the start date. For calendar inventories, they often include it.
