Understanding Time Zones

Time zones are regions of the Earth that have the same standard time. They are generally defined by their offset from Coordinated Universal Time (UTC). Our directory includes46+ commonly used time zone abbreviations across 7 regions.

Popular time zones include EST (Eastern Standard Time) used in cities like New York, PST (Pacific Standard Time) for Los Angeles, GMT (Greenwich Mean Time) for London, and JST (Japan Standard Time) for Tokyo.

How Time Zones Work

The Earth is divided into 24 time zones, each approximately 15 degrees of longitude wide. UTC (Coordinated Universal Time) serves as the primary time standard from which all other time zones are calculated. Time zones to the east of the Prime Meridian (0° longitude) add hours to UTC, while those to the west subtract hours.
