Time Zone Meeting Planner
Find the best meeting time across multiple time zones.
Calculate UTC offsets and find overlapping business hours for global teams.
Coordinating meetings across time zones is one of the most common challenges for global teams, remote workers, and international businesses. Getting the time wrong means some team members are awake at 3 AM or miss meetings entirely.
Understanding UTC
UTC (Coordinated Universal Time) is the world’s time standard — all time zones are expressed as offsets from UTC. For example:
- New York (EST): UTC−5 (UTC−4 in daylight saving)
- London (GMT/BST): UTC±0 (UTC+1 in summer)
- Paris (CET/CEST): UTC+1 (UTC+2 in summer)
- Dubai (GST): UTC+4 (no daylight saving)
- Mumbai (IST): UTC+5:30
- Singapore (SGT): UTC+8
- Tokyo (JST): UTC+9 (no daylight saving)
- Sydney (AEST/AEDT): UTC+10 (UTC+11 in summer)

The “Friendly Hours” Problem
The challenge is finding a time that falls within normal working hours (9 AM – 6 PM) for all participants. For some combinations (e.g., New York and Tokyo are 13 hours apart), there is no overlap in business hours — someone must compromise.
Best Practice for Difficult Combinations
When there’s no overlap, rotate the inconvenient time fairly across team members rather than always making the same person take the early or late call. Record meetings and share recordings for those who cannot attend live.
