Why the Working Days Calculator is different
Browser-native
The Working Days Calculator runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.
No artificial limits
No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.
Production-grade quality
Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
Common use contexts
- Project deadline math — "5 working days from today"
- Vacation planning — counting working days off vs total days
- Payroll period — counting workable days in a month
- Contract / SLA calculations
Private and secure
