Business Days Calculator
Count working days between two dates, skipping weekends and any public holidays you list.
About the Business Days Calculator
Enter a start and end date, choose which days are your weekend, and list any public holidays as dates (YYYY-MM-DD). The calculator counts working days, weekend days and holidays between the two dates, counting both ends.
Use it for project deadlines, notice periods, delivery estimates and payroll. Holidays differ by country, state and company, so add the ones that apply to you.
The formula
Working days = calendar days − weekend days − holidays on weekdays
Worked example
2 November to 31 December 2026, Saturday–Sunday weekend, holidays 26 November and 25 December
- 60 calendar days, counting both dates
- 16 weekend days and 2 holidays
- 42 working days
Things to keep in mind
- A holiday that falls on a weekend isn't counted twice; if your employer moves it to a weekday, add that day instead.
