Time

Hawaii is a long way from anywhere not just in air-miles but time too. But here is our handy guide to working out what is going on, when. Hawaii runs on Hawaiian Standard Time which is 10 hours behind GMT. There is no daylight saving time during the northern hemisphere summer therefore it can get a bit confusing working out what time it is in relation to the rest of the world. You can safely assume that Hawaii is 'behind' almost everywhere on the globe, but sometimes it is easier to think of us being ahead few hours, but simply on the previous day!
