Understanding Time Zones

Time zones are regions of the Earth that observe the same standard time. The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. Most time zones are offset from Coordinated Universal Time (UTC) by whole hours, though some use half-hour or quarter-hour offsets.

Common Time Zone Abbreviations

Daylight Saving Time (DST)

Many regions observe Daylight Saving Time, moving clocks forward by one hour during warmer months. This is why some zones have two abbreviations (like EST/EDT or PST/PDT). Not all countries observe DST, and the dates of changes vary.
