What is UTC and how does it relate to GMT?

UTC (Coordinated Universal Time) is the primary atomic time standard used globally. GMT (Greenwich Mean Time) is a time zone observing UTC+0 with no daylight saving offset.

Can I convert meeting times across more than two cities?

Yes. You can add multiple international cities to the comparison dashboard to view local times across all participants at once.

How do I find the best time for a cross-border video call?

Use the interactive hour slider to find overlapping business hours (9 AM - 5 PM local time) across all participant time zones.
