What are the best hours to schedule a call between HST and WIB?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Hawaii and Jakarta are 17 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| HST | WIB | Working hours | Note |
|---|---|---|---|
| 2:00 pm | 7:00 am the next day | HST only | afternoon in Hawaii, early morning in Jakarta |
| 3:00 pm | 8:00 am the next day | HST only | afternoon in Hawaii, mid morning in Jakarta |
| 4:00 pm | 9:00 am the next day | both sides | afternoon in Hawaii, mid morning in Jakarta |
Does daylight saving change HST to WIB?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
Western Indonesia Time does not move its clocks at all, so its UTC+7 offset holds every day of the year.
Is HST ahead of or behind WIB?
HST is behind WIB by 17 hours: when it is 12:00 pm in Hawaii, it is 5:00 am the next day in Jakarta. Neither Hawaii Standard Time nor Western Indonesia Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Hawaii Standard Time covers Hawaii, which has never moved its clocks. Western Indonesia Time covers Jakarta, Bandung and Medan, the most populous of the three Indonesian zones. The identifiers behind them are Pacific/Honolulu and Asia/Jakarta, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
