Plan a meeting across time zones
Enter each location's IANA time zone and working hours. The planner checks the chosen date minute by minute as real UTC instants and lists the start times when everyone is inside their own local hours. When nothing fits, it shows who would have to stretch.
Worked example
Everyone keeps their working hours
- Date
- January 15, 2026
- Working hours
- America/New_York · 09:00–17:00Europe/London · 09:00–17:00Asia/Tokyo · 09:00–17:00
- Shared window (UTC)
- No shared time
If one location is flexible
- Flexible location: America/New_York
- No shared time
- Flexible location: Europe/London
- No shared time
- Flexible location: Asia/Tokyo
- 14:00–17:00 UTC · 23:00–Jan 16 02:00 (UTC+09:00)
- Least-bad option
- 14:00–14:30 UTC
- Local times
- America/New_York · 09:00–09:30 (UTC−05:00)Europe/London · 14:00–14:30 (UTC+00:00)Asia/Tokyo · 23:00–23:30 (UTC+09:00)
How it works
- Working hours are local and repeat every day. A shared window exists only where all of them overlap in UTC, and the whole meeting must fit inside it, so a 3-hour overlap offers fewer start times for 60 minutes than for 30.
- In January, Tokyo's 09:00–17:00 ends at 08:00 UTC, before London opens at 09:00 UTC, so no 09:00–17:00 time works for New York, London and Tokyo together.
- The least-bad option keeps everyone else's hours and lets one location be flexible. In recurring meetings, rotate that role so the same team does not always join late at night.
