Working Days Calculator – Calculate Business Days Between Dates

Counts the number of business working days between two dates, with configurable weekend exclusion and support for entering custom public holidays. Essential for project planning, SLA tracking, payroll calculation, and any scheduling context where only weekdays matter.

Common Use Cases

  • Count business days for a project deadline
  • Calculate payment terms (e.g. net-30 working days)
  • Verify SLA compliance windows
  • Plan sprint cycles excluding public holidays

How to Use

  1. Set the Start Date and End Date using the date pickers.
  2. Toggle the Saturday and Sunday chips to include or exclude them.
  3. Optionally enter public holiday dates (one per line, YYYY-MM-DD format) in the text area.
  4. Click Calculate — the result shows working days and a breakdown of skipped days.

Tips & Notes

Note: Both start and end dates are inclusive in the count.

Note: Holiday dates must be in ISO format: YYYY-MM-DD (e.g. 2025-12-25).

Note: The default range on load is today + 30 days as a convenient starting point.
