Calculate the number of working days between two dates in the USA, accounting for weekends and federal holidays. This calculator helps businesses, project managers, and individuals plan schedules accurately.
How to Use This Calculator
To calculate working days in the USA:
- Enter the start date in the "Start Date" field
- Enter the end date in the "End Date" field
- Select whether to include or exclude federal holidays
- Click "Calculate" to get the result
The calculator will display the total number of working days, excluding weekends (Saturdays and Sundays) and optionally excluding federal holidays.
Formula Used
The working days are calculated by:
- Determining the total days between the start and end dates (inclusive)
- Subtracting the number of weekends (Saturdays and Sundays)
- Optionally subtracting federal holidays if selected
For example, if the total days between two dates is 10, and there are 4 weekend days, the initial working days would be 6. If federal holidays are excluded and there are 2 holidays in that period, the final working days would be 4.
