Workdays Calculator
Count working days between two dates, excluding weekends and holidays.
What is Workdays Calculator?
The Workdays Calculator counts the number of working days — excluding weekends and optionally public holidays — between two dates. This is a staple tool for business professionals, HR departments, legal teams, and project managers who need to calculate deadlines, notice periods, and delivery windows in business days rather than calendar days.
The distinction between calendar days and business days is legally and contractually significant. A contract that allows '30 business days' for a response is very different from '30 calendar days.' Project timelines expressed in business days need to account for weekends and holidays to produce accurate delivery estimates. Payroll teams calculate pay periods and leave balances in working days. The Workdays Calculator handles all these scenarios quickly and accurately.
Many implementations allow you to specify which country's public holidays to exclude, making the tool reliable for international teams working across different regional holiday calendars.
