The calculator finds the difference between two dates – as a total number of days, in weeks, broken down into years/months/days, and as a number of business days.
- Business days: Counts only Monday to Friday (excluding public holidays).
- Order does not matter: The earlier date is automatically taken as the start.
- Use: Deadlines, holiday days, project durations or "X days until…".
