Input tips
- Use ISO formats like 2024-09-20T14:00 to avoid ambiguity.
- For simple clock math, just enter times like 1:30pm and 6:45pm.
- Mixing time zones? Include offsets (e.g., 2024-05-01 09:00 -04:00).
FAQ
- Can I see negative durations?
- The tool always shows the absolute difference but flags when the end precedes the start so you can adjust accordingly.
- How precise are the results?
- Durations are calculated to the millisecond internally, then rounded for display. Seconds show two decimals when needed.
- Does daylight saving time affect calculations?
- Yes. Because Luxon respects time zones, transitions such as DST shifts are accounted for when you include dates and offsets.
