Working Days Calculator
About This Calculator
The working days calculator counts how many business days fall between two dates. It starts from the full span of days, removes every Saturday and Sunday, and then removes public holidays that land on a weekday, leaving the true number of working days.
Working days matter whenever a timeline is measured in business terms rather than calendar terms. Delivery and shipping estimates, service level agreements, payroll and leave calculations, notice periods, and legal or administrative deadlines are usually quoted in working days, because weekends and holidays are not counted. A simple calendar-day count would overstate how much working time there really is — whether you call it a working-days count, a business-days count, or the number of business days between two dates, it's the same figure.
The result breaks the span down so you can see the whole picture: the total days in the range, how many were weekend days, how many were public holidays on weekdays, and the working days that remain. Both the start and end dates are included in the count, and if you enter them in the wrong order the calculator sorts them out and tells you the range was reversed.
Public holidays are loaded from a national holiday list, so a holiday that falls on a weekday is correctly excluded, while one that already lands on a weekend is not double-counted. To use it, choose a start date and an end date and press Count working days. Everything is computed in your browser.
Need to move a date forward instead of counting between two known dates — like finding what day is 10 business days from today? Use the Add Business Days Calculator. If your calculation is specific to India, the Working Days Calculator India uses the Indian national holiday list.
How It Works
- Enter a start date.
- Enter an end date.
- Click “Count working days”.
- View the business days, with weekends and holidays removed.
Formula & Methodology
The result is worked out as follows:
Working days = all days − weekends − public holidays
Every day in the range, including both endpoints, is checked. Saturdays and Sundays are removed, then public holidays that fall on a weekday are removed. A holiday already on a weekend is not counted twice. What remains is the working-day total.
Worked Examples
For Mon 2026-01-05 to Fri 2026-01-09, the result is 5 working days.
For Mon 2026-06-29 to Fri 2026-07-03 (US), the result is 4 working days — Independence Day observed 3 Jul.
For A full calendar week (Mon–Sun), the result is 5 working days, 2 weekend days.
Frequently Asked Questions
Which holidays are excluded?
National public holidays for the selected country, on top of every Saturday and Sunday. Holidays that fall on a weekend are not counted twice.
Are both the start and end dates counted?
Yes — the range is inclusive of both endpoints when counting working days.
Is this the same as a "business days between two dates" calculator?
Yes — working days and business days mean the same thing here. Enter your two dates and it counts the business days between them, holidays excluded.
What if I enter the dates in the wrong order?
The calculator sorts them, returns the correct count, and notes that the range was reversed.
