Best Time to Schedule a Meeting Across Time Zones
Scheduling a meeting across three or more time zones feels like herding cats — someone is always awake at 2 AM. The trick isn't finding a perfect hour (there often isn't one); it's finding the fairest hour and being consistent about it. Here's a practical framework.
The "Fair Window" Method
- List every participant's local working hours (typically 9 AM–5 PM, but adjust for culture — Spain eats lunch 2–4 PM, India works 9:30 AM–6:30 PM).
- Find the intersection. Plot each person's 9–5 on a 24-hour UTC timeline and shade the overlap.
- If no overlap exists, split the pain. Alternate meetings so the same person isn't always at 7 AM or 11 PM.
- Anchor to UTC. State the meeting as "14:00 UTC" so nobody does mental math wrong.
Example: San Francisco + London + Bangalore
| UTC | SF (PT) | London (GMT) | Bangalore (IST) |
|---|---|---|---|
| 08:00 | 12:00 AM | 8:00 AM | 1:30 PM |
| 09:00 | 1:00 AM | 9:00 AM | 2:30 PM |
| 10:00 | 2:00 AM | 10:00 AM | 3:30 PM |
| 16:00 | 8:00 AM | 4:00 PM | 9:30 PM |
| 17:00 | 9:00 AM | 5:00 PM | 10:30 PM |
The only humane slot is 16:00–17:00 UTC = 8–9 AM SF, 4–5 PM London, 9:30–10:30 PM Bangalore (Bangalore takes the late hit — rotate it next time).

- Calendar apps with timezone-aware invites (Google, Outlook).
Frequently Asked Questions
What's the best universal meeting time?
There isn't one for global teams. Aim for 14:00–17:00 UTC, which covers European afternoon + US morning + Asian late evening.
How do I schedule across 3 time zones fairly?
Plot each person's working hours on a UTC timeline, find the overlap, and rotate the "bad" slot if none exists.
Should I use UTC for invites?
Yes. "14:00 UTC" is unambiguous; "2 PM" is not.
What if there's zero overlap?
Asynchronous-first: record the meeting, use shared docs, and hold a short live sync at a rotating time.
Which tool finds the overlap for me?
Our Meeting Planner does it from any two cities.
