📖What is it?

The Time Zone Meeting Planner converts a proposed UTC meeting time into local times for you and up to two other participants in different time zones, using simple UTC offset arithmetic with modulo wrapping for day boundaries.

🎯How to use

Enter the proposed meeting time in UTC (24-hour), then enter the UTC offset for each participant. For example: New York (EST) = -5, London (GMT) = 0, Mumbai (IST) = +5.5, Tokyo (JST) = +9.

💡Example scenario

A meeting at 09:00 UTC. New York (UTC-5) = 04:00, London (UTC+0) = 09:00, Mumbai (UTC+5.5) = 14:30. The modulo math handles midnight crossings automatically.

🏆Pro tip

The global overlap window for synchronous meetings between East Coast USA, Europe, and Asia is typically only 1-2 hours (around 13:00-15:00 UTC). For teams spanning more than 12 time zones, asynchronous communication (recorded video, shared docs) is often more practical than live meetings. Remember daylight saving time shifts can change offsets by 1 hour.
