Frequently Asked Questions

How do I find the best meeting time across time zones?

Find the overlapping business hours by comparing when both locations are within 9 AM - 5 PM. For example, New York (UTC-5) and London (UTC+0) overlap from 9 AM - 12 PM New York time (2 PM - 5 PM London time), giving 3 hours of overlap.

What does UTC mean?

UTC (Coordinated Universal Time) is the world time standard. Time zones are expressed as offsets from UTC. For example, EST (Eastern Standard Time) is UTC-5, meaning it's 5 hours behind UTC. UTC+0 is the same as GMT (Greenwich Mean Time).

Do time zones change with daylight saving time?

Yes, many regions shift their clocks by 1 hour for daylight saving time (DST). The US and Europe change on different dates, which can temporarily alter the time difference between cities. Not all countries observe DST.
