How it works
The tool iterates across the date range and counts days that are not selected as weekend days and are not listed as holidays. Toggle “Include end date” to switch between inclusive and end-exclusive ranges.
Examples
- 2026-03-02 → 2026-03-06 with Sat/Sun weekends (inclusive) → 5 business days
- Add holiday 2026-03-04 → 4 business days
- Exclude Fri/Sat for weekend → matches regions where Sunday is a business day

FAQ
- What is a business day?
A business day is typically Monday through Friday, excluding weekends and (optionally) holidays. This calculator lets you define weekend days and supply a holiday list.
- Does the calculator include the end date?
You can choose. If “Include end date” is enabled, the end date is counted when it is a business day and not a holiday.
- How do I add holidays?
Paste dates in YYYY-MM-DD format (one per line or comma-separated). Those dates will be excluded if they fall on an otherwise counted business day.
- What if my country’s weekend is Friday/Saturday?
You can change the weekend selection to exclude Fri/Sat (or any combination).
- Is any data stored?
No. Everything runs locally in your browser. Inputs are not stored or transmitted.
