Definition

Noun: 1. A designated geographical region that observes a uniform standard time: A "time zone" is one of the 24 longitudinal divisions of the Earth, each approximately 15 degrees wide, within which the same official clock time is used. These zones are established to coordinate timekeeping across regions, accounting for the Earth's rotation.

It is essential for scheduling, travel, and global communication. - Example: "When scheduling the international conference call, we must consider the different time zones of all participants." - Example: "New York is in the Eastern Time Zone (ET), which is UTC-5 during Standard Time."
