Working Days Calculator

Use this working days calculator to count weekdays between two dates. It excludes Saturdays and Sundays, and counts Monday to Friday as working days.

This is useful when you need a quick weekday count for project timelines, delivery estimates, school schedules, payroll periods, support response times, or simple business planning.

How to use the Working Days Calculator

  1. Select the start date.
  2. Select the end date.
  3. Click Calculate.
  4. Review the total working days between the two dates.

What this calculator counts

The calculator counts dates inclusively. That means the start date and end date are included when they fall on Monday, Tuesday, Wednesday, Thursday, or Friday.

For example, Tuesday to Thursday in the same week counts as 3 working days: Tuesday, Wednesday, and Thursday.

What this calculator excludes

This tool excludes weekends only:

  • Saturday
  • Sunday

It does not exclude public holidays, company holidays, school holidays, or custom leave days.

Common use cases

  • Count weekdays for project deadlines.
  • Estimate delivery or processing time.
  • Calculate weekday-only task duration.
  • Check how many workdays are left in a date range.
  • Plan school, office, or support schedules.
  • Compare simple work periods without weekend days.

Working days vs business days

Working days and business days are often used in a similar way, but business days may also exclude public holidays or custom non-working days.

Use this calculator when you only need to remove Saturdays and Sundays. Use the Business Days Calculator when you also need to exclude holidays.

Tips & notes

  • The result is inclusive of the start and end dates.
  • If the end date is earlier than the start date, the calculator still works by counting the range between them.
  • For official deadlines, always confirm whether holidays should also be excluded.
  • Use Days Between Two Dates if you need total calendar days instead of weekdays.
