Business Days Calculator

The Business Days Calculator helps you calculate the number of business days between dates or find a future/past date by adding business days.

Options
Include start date
Use verbose output

How to Use:

This tool figures out business days the working weekdays between two dates, or helps you add/subtract business days from a start date. Weekends are automatically skipped. (Holidays coming soon!)

Choose a mode first:

  • Business Days Between – count how many business days there are from one date to another
  • Add Business Days – add a number of business days to a start date
  • Subtract Business Days – go backward a number of business days

Enter your Start Date, and depending on the mode, either choose an End Date or enter a number of business days. The result updates live with each change.

Toggles let you:

  • Include the start date in the count
  • Use verbose format like “Monday, June 30, 2025” instead of ISO

You can copy the result, export it as a text file, or clear all to reset. The output flashes each time it updates, so you know it’s working.

No data leaves your device. It’s all client-side and instant.

What the Business Days Calculator can do:

It’s perfect when you’re working with real workdays not just raw calendar days. You can plan deadlines, timelines, and task durations more accurately, whether you’re looking at the past or future.
