Why the same minute shows different clocks — illustrated
Every time zone is UTC plus a fixed offset — the number of hours and minutes it sits ahead of (or behind) UTC. London is UTC+1 in summer, New York is UTC−5, Shanghai is UTC+8. The instant is identical; only the offset shifts how it is written on each wall clock.
Offsets are whole or half hours (India uses UTC+5:30). Daylight saving moves the offset twice a year — which is why UTC is the stable reference this tool and every computer aligns to.
You want a call that fits everyone's working day (09:00–18:00). UTC 14:00 lands inside the window for all three.
- London (UTC+1):14:00 UTC + 1h = 15:00 — mid-afternoon ✅
- New York (UTC−5):14:00 UTC − 5h = 09:00 — just-starting morning ✅
- Shanghai (UTC+8):14:00 UTC + 8h = 22:00 — after work ✗
- Pick UTC 09:00:→ SH 17:00 · NY 04:00 ✗, so 14:00-UTC was the sweet spot
