Time in Hawaii, live, and always UTC-10.

The time in Hawaii is Hawaii Standard Time, HST, which is UTC-10. Hawaii does not observe daylight saving time, so its clock stays at UTC-10 all year. That means the gap between Hawaii and the mainland changes twice a year, because the mainland moves and Hawaii does not. The big clock above is Hawaii time to the second, and the cards show the offset and your own gap.

How to use this Hawaii time page

1. Read the big clock: hours, minutes and seconds in Hawaii, then the date, the name of the zone and its UTC offset.
2. The cards under it show the time zone, the UTC offset, whether the place changes its clocks and when next, and the difference from your own time zone. If the page has guessed your zone wrong, pick the right one under Your place.

What the official sources say

The US Department of Transportation says daylight saving time is not observed in Hawaii, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Virgin Islands and most of Arizona. In 49 CFR Part 71, section 71.12, the Hawaii-Aleutian standard time zone includes the entire State of Hawaii. The IANA time zone database holds Pacific/Honolulu at UTC-10 with no daylight saving rule now in use, and the page reads that data from your browser. Checked 18 Oct 2026.

Hawaii compared with the mainland

Hawaii stays at UTC-10 all year, so the gap to each place that changes its clocks is one hour smaller in winter than in summer. The table shows how far Hawaii is ahead of or behind each place in the middle of January and July 2026.

Los Angeles is the closest: 2 hours ahead of Hawaii in winter on PST, and 3 hours ahead in summer on PDT. Phoenix does not change its clocks either, so the gap between Hawaii and Phoenix is always 3 hours. Tokyo is far ahead, and for a call that means a date change: when it is 8 AM Monday in Hawaii it is 3 AM on Tuesday in Tokyo.

A morning in Hawaii, on the mainland clock

For 8:00 AM in Hawaii on a day in July and a day in January, the mainland clocks read:

The arithmetic for New York in July: 8:00 AM HST is 6:00 PM UTC (add 10 hours), and New York is on EDT, 4 hours behind UTC, so it is 2:00 PM. In January New York is on EST, 5 hours behind UTC, so it is 1:00 PM.

Planning a call with Hawaii

Hawaii works the same 9 to 5 on a clock that is 5 or 6 hours behind New York, so calls with the East coast fit only a few hours: Hawaii 9:00 AM to 11:00 AM is 3:00 PM to 5:00 PM EDT in summer. Calls with the West coast fit more of the day. Check the strip of eight times above, set to your own place, to see which hours of your day line up.

One clock for the whole state

All the islands share the Hawaii-Aleutian zone as set out in the federal regulation, so Honolulu, Maui, Kauai and Hawaii Island show the same time. The page uses the Honolulu zone from the IANA database.

What changes for Hawaii when the mainland moves

Nothing changes in Hawaii. In March the mainland moves forward, so the gap grows by one hour, and in November it moves back and the gap shrinks. A call at 2:00 PM in New York is 8:00 AM in Hawaii in summer, when New York is on EDT and 6 hours ahead, and 9:00 AM in winter, when New York is on EST and 5 hours ahead. If you keep a standing call with Hawaii, check the first one after the mainland changes its clocks.

Is the clock exact?

The page shows your device clock converted to Hawaii time. If the device clock is a few seconds off, so is the page. The online clock has a Check my clock button that compares your device with the web server.
