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. -
Wellington and Buenos Aires overlap from 8:00 AM to 9:00 AM (Wellington) to the equivalent 5:00 PM to 6:00 PM in Buenos Aires — that's your meeting window. Buenos Aires is 15 hours behind Wellington, which leaves a narrow 1-hour window. Treat 8:00 AM in Wellington (5:00 PM in Buenos Aires) as the time and build around it. Note the day shift — Buenos Aires is on the previous day relative to Wellington while this overlap is open. A quick caveat — Wellington's clocks move for daylight saving and Buenos Aires's don't, so the times here are right for only part of the year.
