About Western Indonesian Time (WIB)

Western Indonesian Time (WIB — Waktu Indonesia Barat, IANA: Asia/Jakarta) is the civil time of western Indonesia, set at UTC+7:00 year-round (no DST). Indonesia spans 3 time zones (WIB UTC+7, WITA UTC+8, WIT UTC+9) covering its 17,508+ island archipelago across ~5,000 km of longitude — the world's largest archipelagic country by area. WIB serves approximately 200 million Indonesian people on Java, Sumatra, West Kalimantan, and Central Kalimantan — including the major population centers. WIB is identical in offset to Indochina Time (ICT) used by mainland Thailand/Vietnam/Cambodia/Laos. Major WIB cities: Jakarta (10.5M city, 35M metro — Indonesia's capital and Southeast Asia's largest metro after Tokyo/Delhi/Shanghai/Manila), Surabaya (2.9M city, 9.3M metro — East Java capital), Medan (2.4M — Sumatra), Bandung (2.5M — West Java), Bekasi (3M — Jakarta satellite city), Tangerang (2.4M — Jakarta satellite), Depok (2.4M — Jakarta satellite), Semarang (1.7M — Central Java), Palembang (1.7M — Sumatra). Affects: IDX (Indonesia Stock Exchange) trading hours, Jakarta KRL commuter-rail schedules, Borobudur Buddhist temple + Prambanan Hindu temple tourism schedules.

About Eastern Standard Time (EST)

Eastern Standard Time (EST, IANA: America/New_York, America/Toronto) is the time zone for the US Eastern Seaboard and Canadian eastern provinces, set at UTC-5:00. EST is the most economically and politically significant US time zone, serving the NYC-Washington DC-Boston-Atlanta-Miami corridor of ~150 million people across the entire US Eastern region (New York, Pennsylvania, Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire, Maine, New Jersey, Delaware, Maryland, Virginia, West Virginia, North Carolina, South Carolina, Georgia, Florida except panhandle, Ohio, Kentucky eastern, Tennessee eastern, Indiana most, Michigan most), eastern Canada (Quebec, Ontario), and the Caribbean (Bahamas, Cuba, Jamaica, Haiti, Panama since 1908). EST observes DST per Energy Policy Act 2005 (switching to EDT = UTC-4:00 from March to November). NYSE official market hours 09:30-16:00 EST/EDT, Wall Street financial reporting, US Federal Government Washington DC working hours, and US Capitol legislative sessions all reference EST/EDT. The historical 'Big Three' US TV-network prime-time was 8-11 PM EST.
