Shared windows are outlined in work green; each participant’s available periods are shown in daylight blue.
- Best compromise: 10:00 to 16:00
Recommended starting point
14:00 UTC · 08:00 Chicago · 14:00 London · 23:00 Tokyo
The best three-way compromise in this example; Tokyo carries the late-hour cost.

How much of the world is awake?
Snapshot · 2026-10-16 07:33 UTC- Working 62% 676m
- Weekend & holidays 8% 92m
- Asleep 22% 235m
- Personal time 8% 86m
population-weighted across 200 major cities — an approximation, not a census. Weekend includes public holidays; "personal time" covers 07–09 and 17–22 local.
Carry-forward risk
DST should be a visible decision, not a surprise.
Daylight-saving timeline

Fairness over time
No one gets every bad meeting.
Recurring meeting fairness
Chicago 32% burden
Two early starts across the series
London 28% burden
Mostly preferred hours
Tokyo 40% burden
Late calls rotate away next week
Lower burden means fewer meetings land outside the participant’s preferred hours.
Team board
Keep the team context ready for the next decision.
Save a people-first board with working hours, weekends, and handoff lanes. No sign-up is required to start with a shareable view.
A shareable event artifact
Send one moment. Let everyone see it locally.
Recipients get a clear local time, the canonical event zone, and calendar actions instead of a stale screenshot.
