Why people convert Indonesia to PST time
- Scheduling a call from Indonesia to PST: a 10:00 AM start in Indonesia lands at 7:00 PM in PST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: Indonesia and PST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PST is 6:00 PM in Indonesia.
- Watching a live event or market open: Indonesia viewers need 6:00 PM in PST to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to Indonesia.
- Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -15h gap is not.
- With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week Indonesia takes the early slot, the next week PST does.
About WIB (Western Indonesia Time)
Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.
About PST (Pacific Standard Time)
Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.
Best time to call between Indonesia and PST
