What are the best hours to schedule a call between WAT and HST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. West Africa and Hawaii 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.
| WAT | HST | Working hours | Note |
|---|---|---|---|
| 6:00 pm | 7:00 am | neither side | evening in West Africa, early morning in Hawaii |
| 7:00 pm | 8:00 am | neither side | evening in West Africa, mid morning in Hawaii |
Does daylight saving change WAT to HST?
West Africa Time does not move its clocks at all, so its UTC+1 offset holds every day of the year.
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
Is WAT ahead of or behind HST?
WAT is ahead of HST by 11 hours: when it is 12:00 pm in West Africa, it is 1:00 am in Hawaii. Neither West Africa Time nor Hawaii Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
West Africa Time covers Lagos, Kinshasa, Luanda and Douala, the most populous zone in Africa. Hawaii Standard Time covers Hawaii, which has never moved its clocks. The identifiers behind them are Africa/Lagos and Pacific/Honolulu, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
