Time Zone Calculator
Convert a time between any two fixed UTC offsets from UTC−8 (Los Angeles) to UTC+12 (Auckland). See the converted time with next/previous-day shifts, plus a meeting-planner table showing what 0:00, 6:00, 12:00 and 18:00 in the base zone feel like for the target zone.

Meeting planner — New York vs London
Business hours = 9:00–17:00 local; awake hours = 7:00–22:00.
This tool uses fixed offsets — it does not model daylight saving time. Add the local DST shift manually (typically +1 h in summer for the zones involved).

Formula
target time = base time + (target offset − base offset), wrapped modulo 24 h
Pro tips
- • For recurring meetings, pick 8:00 or 17:00 in the easternmost zone — 0:00 conversions wreck sleep schedules.
- • India (UTC+5:30) and Nepal (UTC+5:45) use half-hour offsets — adjust manually.
