Asia/Jakarta is the IANA time zone identifier for the western part of Indonesia, anchored by the capital city Jakarta. It uses Western Indonesian Time (WIB), which is UTC+07:00 year-round. This zone does not observe daylight saving time, providing a constant offset for its millions of inhabitants and businesses.
Overview and Coverage
Asia/Jakarta applies to the western and central regions of Indonesia, including the islands of Sumatra, Java, and West Kalimantan. It is one of three time zones used in Indonesia, the others being Asia/Pontianak (WITA, UTC+08:00) and Asia/Jayapura (WIT, UTC+09:00). The zone covers major cities such as Jakarta, Surabaya, Bandung, Medan, and Palembang. It is the most populous time zone in Indonesia, serving over 150 million people.
Offset and Abbreviation
The standard offset is UTC+07:00, abbreviated as WIB (Waktu Indonesia Barat, or Western Indonesian Time). This offset is 7 hours ahead of Coordinated Universal Time (UTC). For example, when it is 12:00 UTC, it is 19:00 WIB in Jakarta. The abbreviation WIB is used locally and in international contexts.
Daylight Saving Time
Asia/Jakarta does not observe daylight saving time (DST). The offset remains constant at UTC+07:00 throughout the year. Indonesia has never used DST since its independence, and there are no plans to introduce it. This means there is no seasonal clock change, simplifying scheduling and timekeeping.
