Indonesia — three timezones across a huge archipelago
Indonesia spans three timezones — WIB (UTC+7, Jakarta and western islands), WITA (UTC+8, Bali and central islands), WIT (UTC+9, Papua and eastern islands). No DST. Jakarta is the business anchor. The country's three-zone footprint across 3,000 miles east-west means intra-Indonesia business calls need timezone awareness — Jakarta to Bali is 1 h forward, Jakarta to Jayapura is 2 h forward.
