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. -
Both teams are at their desks between 5:00 PM to 6:00 PM in Seattle and 8:00 AM to 9:00 AM in Hong Kong. Hong Kong is 15 hours ahead of Seattle, leaving a tight 1-hour window. Book 5:00 PM in Seattle (8:00 AM in Hong Kong) early and you'll dodge the daily scramble. When booking, note that Hong Kong is on the next day — it's worth spelling out the full date in the invite. A quick caveat — Seattle's clocks move for daylight saving and Hong Kong's don't, so the times here are right for only part of the year. To edit hours, add more timezones, and share with your team, create a free collaborative board.
