How do time zones work?

Time zones are regions of the world that share the same standard time. They are usually defined in relation to Coordinated Universal Time (UTC), such as UTC−5 or UTC+1.

What is UTC?

UTC stands for Coordinated Universal Time. It is the primary time standard used around the world to regulate clocks and time.

What is daylight saving time?

Daylight saving time (DST) is the practice of moving clocks forward by one hour during warmer months to extend evening daylight and then moving them back again in cooler months.

Can I use this tool to plan meetings?
