What are Time Zones?

Time zones are regions of the globe that observe a uniform standard time. The world is divided into 24 time zones, each roughly 15 degrees of longitude apart.

Daylight Saving Time (DST)

Many regions adjust their clocks forward by one hour during summer months. This tool automatically accounts for DST changes.
