About Business Days Calculator

Planning project timelines or delivery dates requires knowing exactly how many working days are available. Our free online Business Days Calculator helps you find the exact number of weekdays between two dates, excluding weekends.

How It Works

The calculator iterates through the date range between your start and end dates. It checks the day of the week for each date, counting only Monday through Friday while skipping Saturdays and Sundays.

Common Use Cases

  • Calculating accurate project deadlines and delivery estimates
  • Determining the number of working days in a specific month or quarter
  • Estimating shipping and transit times for logistics
  • Planning employee leave and vacation days

Frequently Asked Questions

Yes, the calculation is inclusive. If the start date is a Monday and the end date is the same Monday, it counts as 1 business day.
