Working Days Calculator
Count workdays between dates with editable weekends, holidays and endpoint rules.
What Is the Working Days Calculator?
The Working Days Calculator counts included calendar days, workdays, weekend days and manually entered holidays between two dates. Weekend patterns and endpoint inclusion are explicit.
How It Works
Enter the date range, select the weekend pattern, paste any holiday dates and choose whether the endpoints count.
When to Use It
Use it for lead times, service windows, staffing periods and project schedules that do not use a standard Monday-through-Friday calendar.
Frequently Asked Questions
- Are Public Holidays Added Automatically?
- No. Holiday rules vary by country, employer and observed-date policy, so the tool uses the dates you enter.
