How to schedule a meeting across time zones

Scheduling one group is annoying. Scheduling a group spread across time zones is where it truly breaks down. Someone says "let us meet at 10", three people ask "10 whose time?", and a week later you are still trading messages. Here is a calmer way to do it.

Why time zones cause so much pain

Two reasons. First, people naturally think in their own local time, so every proposed time needs mental conversion, and conversions get skipped or done wrong. Second, daylight saving shifts on different dates in different countries, so a slot that worked in March can quietly move by an hour in April. Doing this by hand, for a group, is a recipe for missed calls.

A simple approach that works

1. Let a tool show each person their own local time. Do not send "3pm UTC" and hope. Use a scheduler where every person marks and reads availability in their own timezone, automatically.
2. Aim for the most overlap, not perfect overlap. Across enough time zones, a slot that works for absolutely everyone often does not exist. Find the time the most people can make, and see clearly who cannot, so you can decide whether to shift or record it.
3. Rotate the inconvenient slot. If one region always draws the early-morning or late-night call, take turns. Fairness keeps a recurring meeting alive.
4. Have an async fallback. For the people who genuinely cannot make any live slot, agree on a recording or a written update so they are not blocked.
5. Confirm with a real calendar invite. Once you pick a time, send an invite with an absolute start time so everyone's calendar shows it correctly in their own zone, daylight saving included.

How WhenMost helps

WhenMost was built for exactly this. Everyone paints their availability in their own local time, with daylight saving handled per slot, so nobody converts anything by hand. The results highlight the time the most people can attend and show who is missing, and when you lock it in, everyone can add it to their calendar in one tap.
