About the Working Days Calculator
The Working Days Calculator simplifies project timelines, contract milestone planning, and payroll scheduling by isolating productive business days from total calendar spans. It tallies net working days, weekend days, and statutory public holidays across any date interval. Choose between inclusive and exclusive counting modes, select regional workweek models (such as Monday–Friday, Sunday–Thursday for Middle Eastern markets, or custom active days), import US Federal or UK Bank holiday presets, incorporate custom office closures, and estimate labor costs with the integrated hourly payroll calculator.
