Business Days Calculator
Free business days calculator - 166 countries, no signup
Calculate business days accurately with real public holiday data for 166 countries. Two modes: add or subtract N business days from a date, or count business days between two dates. Automatically handles weekends and national holidays. No account required, no limits, no ads.
Hey Product Hunt
I built this because I kept needing to count business days for contract deadlines, SLA timelines, and renewal dates - and every calculator I found was either wrong (ignored holidays) or too simple (only skipped weekends).
What it does:
- Add or subtract N business days from any date - gets the right answer even across holiday weekends
- Count business days between two dates - with a clear breakdown of what was skipped
- Covers 166 countries with real public holiday data (not a hardcoded US calendar)
- Handles non-standard weekends, Friday–Saturday in Egypt, Saudi Arabia, etc.
- Shareable result URLs - send a calculation to a colleague, they see the same answer
- Free embed - one-line iframe for your blog or help center
The model: Completely free. No signup, no limits, no ads. Built as a public utility.
Who it's for: HR teams, project managers, lawyers, accountants, small business owners - anyone who needs reliable date math.
Would love your feedback - especially if you spot a holiday or weekend rule we got wrong. Accuracy is everything for a calculator.
