If you're planning a phone call home, booking a flight, or trying to catch a Zoom meeting with someone back on the mainland, the first question is usually the same: what time is it in Hawaiʻi right now? The short answer is that Hawaiʻi runs on its own clock, and it's one of the simplest time zones in the country to understand — once you know the one rule that makes it different from almost everywhere else.
What Time Zone Is Hawaiʻi In?
All of the Hawaiian Islands sit in the Hawaiʻi–Aleutian Standard Time zone, abbreviated HST. That's ten hours behind Greenwich Mean Time (UTC-10) year-round. There's no "Hawaiʻi Daylight Time" the way there's a Pacific Daylight Time or Eastern Daylight Time — Hawaiʻi uses the same offset in January as it does in July.
Why Doesn't Hawaiʻi Observe Daylight Saving Time?
Daylight Saving Time exists to shift an hour of daylight from early morning to evening during the long summer days of higher latitudes. Hawaiʻi sits much closer to the equator than the rest of the United States, so its day length barely changes between seasons — sunrise and sunset shift by only about an hour over the course of a year, compared to several hours in places like Seattle or Boston. With so little seasonal swing, there's no daylight to "save," so the state opted out when it adopted the Uniform Time Act in 1967 (Arizona, outside the Navajo Nation, is the only other state that skips it).
How Many Hours Behind Is Hawaiʻi?
Because the mainland shifts clocks twice a year and Hawaiʻi never does, the gap between Hawaiʻi and everywhere else actually changes depending on the season:
- Hawaiʻi to Pacific Time (California, Oregon, Washington): 2 hours behind during Standard Time, 3 hours during Daylight Saving (spring through fall)
- Hawaiʻi to Mountain Time (Colorado, Arizona*): 3 hours behind, or 4 during Daylight Saving
- Hawaiʻi to Central Time (Texas, Chicago): 4 hours behind, or 5 during Daylight Saving
- Hawaiʻi to Eastern Time (New York, Florida): 5 hours behind, or 6 during Daylight Saving
- Hawaiʻi to UK (London): 10 hours behind, or 11 during British Summer Time
That's why a 9 a.m. meeting in New York can land at 3 a.m. or 4 a.m. in Honolulu depending on the time of year — the most common scheduling mistake visitors and remote workers make.
Tips for Scheduling Around Hawaiʻi Time
A few habits make Hawaiʻi time easy to work with instead of confusing:
- Always double-check whether the mainland is currently observing Daylight Saving Time before converting — the gap moves by an hour twice a year even though Hawaiʻi stands still.
- When booking a flight, remember that arrival times are shown in local Hawaiʻi time, so a 6-hour flight that departs at 10 a.m. Pacific can land what feels like only a few hours later on the clock.
- If you're island-hopping on a trip planned around our Islands & Places collection of Hawaiʻi gear, note that every island — Oʻahu, Maui, Kauaʻi, and the Big Island — shares the exact same time zone, so there's no adjusting needed between stops.
- Set your phone to the "Hawaiʻi" time zone manually rather than trusting auto-detect in some hotels and rentals, which can occasionally default to Pacific Time.
Once you've got the ten-hour (or eleven, in summer) offset from the East Coast locked in, Hawaiʻi time stops being a math problem and just becomes part of the rhythm of island life — unhurried, consistent, and refreshingly immune to the clock changes everyone else deals with twice a year.
