About this calculator
This version excludes weekend days based on your choice (default: Saturday and Sunday). Public holiday support may be added later.
The result includes the number of business days, the total counted days in the range, and how many of those days fall on a weekend.
Frequently asked questions
What is a business day?
A business day is any working day. By default that means Monday through Friday, but you can change the weekend pattern to match other regions (for example Friday and Saturday).
Are weekends excluded?
Yes. Whichever days you mark as the weekend are excluded from the business day count. Saturday and Sunday is the default.
Are public holidays excluded?
Not yet. The current version only handles weekends. We may add country-specific holiday support in a future update.
Can I include or exclude the start or end date?
Yes. Use the "Include start date" and "Include end date" checkboxes to control whether either endpoint is counted.
Can I calculate working days between two dates?
Yes. Choose your start and end dates and the calculator returns the number of working days in that range.
