Frequently Asked Questions
Are both the start and end dates included in the business day count?↓
Yes. In corporate project scheduling and sprint planning, both the commencement day and the completion date represent active working days when falling on a weekday.
What happens if a statutory holiday falls on a weekend?↓
If a bank holiday falls on Saturday or Sunday, employers typically observe it on the preceding Friday or following Monday. Only count holidays that fall on actual working weekdays.
Can this tool calculate working days for a 7-day operation?↓
Yes. Simply turn off the "Exclude Weekends" toggle. The tool will calculate total calendar days minus only your specified downtime or holiday closures.
What limitation should I note regarding regional statutory bank holidays?↓
Statutory bank holidays differ across countries, provinces, and states (e.g. US Federal vs UK Bank Holidays vs Canadian Provincial). Entering the exact number of observed local holidays provides pinpoint accuracy.
