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. -
Hong Kong and Seattle overlap from 8:00 AM to 9:00 AM (Hong Kong) to the equivalent 5:00 PM to 6:00 PM in Seattle — that's your meeting window. Seattle is 15 hours behind Hong Kong, leaving a tight 1-hour window. Book 8:00 AM in Hong Kong (5:00 PM in Seattle) early and you'll dodge the daily scramble. Note the day shift — Seattle is on the previous day relative to Hong Kong while this overlap is open. Note the seasonal wrinkle: when Seattle is on daylight saving and Hong Kong isn't, the gap between them grows or shrinks by an hour.
