Working Days Calculator
Count the number of business (working) days between two dates, excluding weekends.
Count business days (weekdays) between two dates, excluding Saturdays and Sundays. Built for SLAs, project deadlines, payroll processing windows, and legal notice periods that specify "business days."
Calendar day counts overestimate timelines when weekends do not count — a 10 calendar-day span may be only 8 working days. This distinction matters for shipping guarantees, contract clauses, and HR policies.
Select start and end dates; the calculator skips weekends automatically. For public holidays, subtract those manually or add buffer days based on your country's calendar.
Pair with our Date Difference Calculator for total calendar days. Free, no sign-up.
