Frequently Asked Questions
How do I count business days for a leave request?
Enter start and end dates: a Monday-to-Friday span counts 5 per week, so 20 leave days need 28 calendar days. Weekends exclude automatically — check the result against your HR calendar for public holidays, which vary by state.
Are public holidays excluded too?
Weekends exclude automatically; public holidays vary by country and state, so verify the count against your company holiday list. For payroll, add the holiday dates back in manually before finalizing.
Can I count backwards from a deadline?
Yes — swap the dates to measure working days remaining. A Friday deadline from Monday morning leaves 5 business days; plan review buffers inside that count, not after it.
Is my date data sent anywhere?
No — all math runs locally in your browser. Dates never leave your device, and the tool needs no account.
