Working Days Calculator
Delivery promises often say ten working days, leave policies count weekdays only, and court rules skip Saturdays and Sundays even when calendar days keep ticking. This working days calculator counts Monday-through-Friday days between two dates, excluding standard weekends without you highlighting each Saturday on a wall calendar.
Toggle inclusive end day when your policy counts both the start and end dates as working days inside the range-common in HR and procurement language. The tool is intentionally simpler than the business days calculator: fixed weekend exclusion, no holiday list maintenance, perfect for quick SLAs that only mention weekdays. Project managers estimating sprint capacity, employees checking how many onsite days fall in a window, and anyone translating five business days into real dates use it daily. Calculations remain on your device. Legal assistants counting filing windows and purchasing teams verifying vendor SLAs both save time versus highlighting cells in a spreadsheet manually.
How to Use

- Enable Include end day if both boundary dates should count.
- Click Count working days for the Monday-Friday total.
