We tested each tool with real global team coordination.
Rotate meeting times so the same people do not always have early or late calls. Use tools like Clockwise to optimize automatically. Record meetings for those who cannot attend live.
For US and Europe, 8-11am ET works. For US and Asia, options are limited - often early morning or late evening for one side. Consider async communication to reduce overlap needs.
Set working hours in your calendar. Use tools like Timezone.io or There to make times visible. Add timezone to Slack profile. Communicate explicitly about availability.
Using a standard timezone (like UTC or company HQ) for documentation helps. But schedule actual meetings in local times and rotate who takes inconvenient slots fairly.
