Questions
How is daylight saving handled?
The inputs are local date-times, so the elapsed duration follows the browser's timezone rules.
Can I get a negative result?
Yes. If the end is before the start, the human duration is shown with a minus sign.
Does it count business days?
No. It reports calendar duration; business-day counting depends on holidays and locale.
