How to use Meeting Time Zone Planner
Search actual UTC instants in a 24-hour UTC day. Each 15-minute block and its final instant must fit every participant’s local clock window, using IANA DST rules.
- Enter utc day to search, participant json: zone, start, end, meeting duration (minutes, multiple of 15).
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
Good to know
- 2–8 participant windows, 15-minute clocks, duration 15–480 minutes. Search date 2000–2100; local windows repeat daily, including overnight windows. No holiday, weekday, invitation, or personal calendar access. Browser time-zone database governs DST.
- Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
