How it works
The calculator iterates through each day between the start and end dates. In weekdays-only mode, it counts only Monday through Friday. In all-days mode, it counts every calendar day including weekends.
Both boundary dates are included in the count. This is the same method used in project management software, payroll systems, and legal deadline calculations.
Practical example
From January 1 to January 31, 2026 there are 31 calendar days but only 22 weekdays (workdays).
If you have a 10-business-day deadline starting Monday January 5, the deadline falls on Friday January 16. This is critical for contracts, shipping estimates, and sprint planning.
