Frequently asked questions
- What counts as a working day?
- By default, any weekday (Monday through Friday). You can add specific public holidays to exclude them too.
- Are both the start and end dates included?
- Yes. The count is inclusive on both ends — if start and end are the same weekday, the result is 1 working day.
- Can I count just weekend days instead?
- Turn off 'Exclude weekends' to count every day in the range, then look at the 'Weekend' tile for weekend-day count.
- How do I add holidays?
- Click '+ Add holidays' and paste dates in YYYY-MM-DD format, separated by commas, spaces, or newlines.
- Is my data sent anywhere?
- No. Everything runs in your browser. Dates and holiday lists never leave your device.
