Understanding Time Zones

UTC and GMT

UTC (Coordinated Universal Time) is the primary time standard. GMT (Greenwich Mean Time) is often used interchangeably with UTC, though technically GMT is a time zone and UTC is a time standard.

Daylight Saving Time

Many regions observe daylight saving time, advancing clocks by one hour during summer months. This affects the time difference between zones during different seasons.

Time Zone Offsets

Time zones are expressed as offsets from UTC. For example, EST is UTC-5, while JST is UTC+9. Our converter automatically handles these calculations.

International Date Line

Crossing the International Date Line can change the date as well as the time. Our converter accounts for date changes when converting between distant time zones.
