Gilbert Island Time (GILT)

Gilbert Island Time (GILT) operates at UTC+12 hours, serving as the official time zone for the Gilbert Islands group in Kiribati, including the capital Tarawa. Sometimes simply referred to as "Gilbert Time," GILT does not observe daylight saving time and remains constant throughout the year.

Importance and Global Use of GILT

Gilbert Island Time is essential for managing government operations, education, public services, and transportation across the Gilbert Islands, where most of Kiribati's population lives. Its stable UTC+12 offset ensures consistency and simplifies coordination within the islands, helping maintain social and economic stability.

Internationally, GILT supports scheduling with airlines, shipping routes, and international partners across the Pacific. By providing a clear and predictable time standard, it helps facilitate communication, trade, and development cooperation between Kiribati and other countries in the region.
