Hawaii Time - How to Know What Time It Is In Hawaii

Find out about the Hawaii time zone and Hawaii time difference from the mainland

By

What is the time in Hawaii? What is the Hawaii time difference from various places in the mainland USA?

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.

On our first trip to Hawaii many years ago, my wife and I decided to call my father after dinner. It was around 9:00 p.m. What we forgot was that it was 3:00 a.m. on the east coast where he lived. We woke him up in the middle of the night!

So let's begin.

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.

You can view a great map of the world time zones at www.worldtimezone.com/ and learn more about the world's time zones from About.com's geography Guide Matt Rosenberg.

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 in Hawaii

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.

For geography buffs, the time in Hawaii is also the time in the Cook Islands, Tahiti, and the Aleutian Islands of Alaska.

So just what time is in in Hawaii in the various time zones of the United States? Aside from most of Arizona, which does not observe daylight saving time, here are the times for the balance of 2011 and 2012:

Hours of Daylight in Hawaii

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 and 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 vise versa) does come much quicker.
