Frequently Asked Questions
How are business days calculated?
Business days count the weekdays (Monday through Friday) between two dates, excluding Saturday and Sunday. The tool does not currently factor in public holidays, as these vary by country and region.
Which date formats are supported?
The tool uses a standard date picker that accepts ISO 8601 format (YYYY-MM-DD). You can select dates directly or type them in, and the calculator handles the parsing locally.
