The same digits can be twelve hours apart
On 27 October 2026, 09:00 New York is 21:00 Shanghai. The clocks differ by twelve hours, so an unlabeled 12-hour time can be misleading. Keep AM or PM, the date, and the UTC offset visible when discussing the proposed start.

Find a window for the whole meeting
On 3 November the same New York start is 22:00 Shanghai. The illustrative 09:00–17:00 days have no shared interval. If the teams choose an evening exception, preview the duration and rotate the inconvenience where appropriate; the conversion itself cannot choose a fair arrangement.
Make the plan specific
- Enter each participant’s actual working days and hours. The 09:00–17:00 examples here are editable assumptions, not local business-hour facts.
- Choose a duration from 15 to 240 minutes and check both local end times.
- For a weekly meeting, choose one anchor city and review all twelve dates. Resolve repeated or missing local times explicitly.
Reversing the base city changes how you enter the meeting, not the pair’s information page. Share the configuration or export the resolved event after the participants agree on the time.
