How Time Zones Work

The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. UTC (Coordinated Universal Time) is the primary time standard. Time zones are expressed as offsets from UTC, such as UTC-5 for Eastern Standard Time (EST) or UTC+9 for Japan Standard Time (JST).

FAQ
