Stop Doing Math Before Meetings: The Ultimate Guide to Managing Global Time Zones
Mental gymnastics to figure out what time it is in Tokyo? You're doing it wrong. Here's why your team needs a visual time zone board, not a calculator. -
Shoot for 8:00 AM to 10:00 AM in Osaka; your Seattle colleagues will see that as 4:00 PM to 6:00 PM. Seattle is 16 hours behind Osaka, so common hours are scarce (about 2 hours). Lock the slot, keep it short, and follow up in writing. Because of the gap, Seattle is already on the previous day, so confirm you're both talking about the same calendar date. For part of the year the maths changes: Seattle observes daylight saving, Osaka does not, shifting the overlap by an hour. To edit hours, add more timezones, and share with your team, create a free collaborative board.
