What are the best hours to schedule a call between HST and WAT?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Hawaii and West Africa are 11 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 | WAT | Working hours | Note |
|---|---|---|---|
| 7:00 am | 6:00 pm | neither side | early morning in Hawaii, evening in West Africa |
| 8:00 am | 7:00 pm | neither side | mid morning in Hawaii, evening in West Africa |
Does daylight saving change HST to WAT?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
West Africa Time does not move its clocks at all, so its UTC+1 offset holds every day of the year.
Is HST ahead of or behind WAT?
HST is behind WAT by 11 hours: when it is 12:00 pm in Hawaii, it is 11:00 pm in West Africa. Neither Hawaii Standard Time nor West Africa 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. West Africa Time covers Lagos, Kinshasa, Luanda and Douala, the most populous zone in Africa. The identifiers behind them are Pacific/Honolulu and Africa/Lagos, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
