Business & Commerce

Jakarta, Indonesia's capital and one of the largest metropolitan areas in the world, operates on Western Indonesian Time (WIB, UTC+7) year-round with no daylight saving time. Indonesia spans three time zones — WIB (UTC+7) for western islands including Java and Sumatra, WITA (UTC+8) for Bali and the central islands, and WIT (UTC+9) for Papua and eastern Indonesia — but Jakarta's WIB serves as the national economic reference time. At UTC+7, Jakarta shares its offset with Bangkok and is seven hours ahead of London and twelve to thirteen hours ahead of New York. The Indonesia Stock Exchange (IDX), headquartered in Jakarta, is one of Southeast Asia's larger equity markets. Indonesia's role as one of the world's largest exporters of thermal coal, palm oil, nickel, and copper means Jakarta's business day is a scheduling reference for global commodity trading operations.
