Questions fréquentes
- How are DST transitions handled?
- When a date range crosses a DST boundary, the actual elapsed time may be 23 or 25 hours for a 'one day' span. The calculator uses absolute time difference (UTC) for duration and calendar difference for day count — clarify which you need.
- the calculator prend-il en charge business days ?
- Basic calculators exclude Saturday and Sunday. Holiday exclusion requires a holiday calendar (which varies by country/region). For precise business-day calculation, use a library with a holiday dataset for your jurisdiction.
