Why time zones trip people up
There are 38 inhabited UTC offsets in use today, from UTC−12 to UTC+14, and about 70 countries shift their clocks for daylight saving. A meeting that works in March can silently move by an hour in April when one side springs forward and the other does not. Remote teams, freelancers with overseas clients, and families spread across continents all run into the same problem: a single wrong assumption about "3pm" can mean a missed call.
The safe habit is to always pin a time to a specific city and date rather than a bare offset like "GMT+3" — offsets change with the seasons, but a city plus a date is unambiguous.
How to pick a meeting time
- Look for a slot inside 8:00–18:00 local time for every participant (green cards above).
- When no perfect slot exists, rotate the inconvenience — alternate who takes the early or late call.
- Send calendar invites with the time zone attached so software converts it for each attendee.
- Recheck the week daylight saving starts or ends in any participant's country.
