Knowing the time in Hawaii is important for any visitor to Hawaii, but it's even more important to know how Hawaii time differs from the time back home on the mainland.
It's not uncommon for visitors to get so excited by their first days in Hawaii that they decide to call home and tell their visitors how much fun they are having. The problem is that if you wait until after dinner in Hawaii and you happen to live on the east coast, you'll be calling your friends or relatives in the middle of the night! It's not something that you'll want to do.
So let's begin to look at the time in Hawaii as compared to other major time zones.
On the world clock, Hawaii is 10 hours behind Coordinated Universal Time (abbreviated UTC) and formerly known as (GMT) or Greenwich Mean Time. However, unless you live in England or Europe, that probably means very little to you.

For residents of the United States, Hawaii is in the Hawaii-Aleutian Time Zone, often just called the Hawaii Time Zone, and abbreviated (HST).
No Daylight Saving Time
Hawaii does not observe daylight saving time, so the time difference between Hawaii and all mainland areas that do observe daylight saving time varies depending on the time of year.

Hours of Daylight
The daylight hours in Hawaii are a bit shorter than on the mainland in summer, but significantly longer than the mainland in winter.
In the summer sunrise is usually a few minutes later than on the mainland but can set over an hour and a half earlier than back home.
In winter, however, because of its proximity to the equator, sunrise is usually a few minutes earlier than on the mainland but can set over an hour and a half later.
Also, as many visitors observe, there is less twilight in Hawaii than on the mainland. The sun does rise and set faster, so daylight to darkness (and darkness to daylight) does come much quicker.
