Hawaii Time Zone: HST, No Daylight Saving, and Mainland Gaps

Hawaii keeps its clocks on Hawaii-Aleutian Standard Time (HST), which runs 10 hours behind Coordinated Universal Time (UTC-10) every day of the year. The state does not observe daylight saving time. When the mainland springs forward in March and falls back in November, clocks in Honolulu, Hilo, Kahului and Lihue stay where they are.

Because of that one policy, the gap between Hawaii and the mainland changes twice a year. In winter, Honolulu runs 2 hours behind Los Angeles and 5 hours behind New York. From the second Sunday in March to the first Sunday in November, those gaps grow to 3 and 6 hours.

For households researching a move, the time zone matters day to day. It decides when a remote employee logs on, how late a call to family in Ohio can run, which red-eye flights make sense, and how many days the body needs after landing. This article covers each of those with the numbers relocating households actually plan around.

What time zone is Hawaii in?

Hawaii uses Hawaii-Aleutian Standard Time, abbreviated HST, at a fixed offset of UTC-10. Under federal law the zone is called Hawaii-Aleutian because it also covers the far western Aleutian Islands of Alaska. Phones, laptops and calendar apps usually list it under the database name “Pacific/Honolulu.”

The Aleutian part of the zone does observe daylight saving time. Communities west of 169°30′W longitude shift to Hawaii-Aleutian Daylight Time (UTC-9) each summer. So the two regions share a zone name but show different clocks for about eight months of the year. Hawaii stays on standard time all year.

Every island shares one clock

All eight main Hawaiian islands run on the same time. Oahu, Maui, the Big Island, Kauai, Molokai and Lanai never differ by even a minute. Travelers on interisland flights between Honolulu and the neighbor islands never need to reset a watch, even though the chain spans more than 300 miles from Kauai to the Big Island.

State and county offices also run on HST. That includes the City and County of Honolulu and the County of Hawaii, whose posted office hours and online appointment slots are always in local time. For the roughly 1.46 million residents counted in the 2020 census (see Census QuickFacts), one clock covers the whole state.

Why Hawaii does not observe daylight saving time

Hawaii’s exemption goes back to federal law. Before the 1960s, daylight saving was a patchwork. Individual cities and states picked their own start and end dates, and transportation schedules suffered for it. Congress responded with the Uniform Time Act of 1966, which set a single national daylight saving calendar starting in 1967.

The 1966 Uniform Time Act opt-out

The act included an escape clause. Any state could exempt itself from daylight saving by passing a state law, as long as the whole state stayed on standard time. Hawaii’s legislature used that clause in 1967, the first year the federal rule applied. Arizona followed in 1968. Those two remain the only states fully exempt today.

Federal law allows a state to opt out of daylight saving. It does not allow a state to adopt daylight time permanently. That point matters every time permanent daylight saving comes up in Congress, and it explains why Hawaii’s arrangement has stayed legally simple for nearly six decades.

Latitude does most of the work

The practical reason is geography. Honolulu sits at about 21°N, much closer to the equator than any mainland city. Day length barely changes over the year, so moving an hour of daylight from morning to evening gains very little. In Seattle, the summer change shifts a lot of daylight. In Honolulu, it would mostly mean darker mornings.

With only about 2.5 hours of difference between the longest and shortest days, Honolulu’s sunrise moves just from about 5:50 am in June to about 7:10 am in January. If the state used daylight saving, winter-adjacent mornings in March and early November would stay dark until after 7:30 am, which is hard on school commutes.

Earlier experiments with the clock

Hawaii has tried other arrangements. In 1933 the territory adopted daylight saving and repealed it after about three weeks. During World War II the islands ran on year-round “war time.” Before June 1947, Hawaii’s standard time sat at an unusual 10.5 hours behind UTC. The territory then moved to the round UTC-10 offset it still uses.

Could federal changes affect Hawaii?

The Sunshine Protection Act, which would make daylight saving permanent nationwide, passed the U.S. Senate by unanimous consent in March 2022 but stalled in the House. It has been reintroduced since. Versions of the bill let exempt states such as Hawaii and Arizona keep standard time. As of October 2026, nothing has become law.

If permanent daylight saving ever passes, Hawaii’s gaps would lock at their summer values: 3 hours to the West Coast and 6 hours to the East Coast all year. Local coverage of the issue appears from time to time in Honolulu Civil Beat and the Honolulu Star-Advertiser.

The Hawaii-to-mainland time gap, season by season

Because only the mainland moves its clocks, the gap to Hawaii grows by one hour in spring and shrinks by one hour in fall. Arizona is the exception. It also skips daylight saving, so its gap with Hawaii stays at 3 hours all year. Alaska, the nearest state by clock, is 1 or 2 hours ahead.

Switch dates for 2026 and 2027

Mainland daylight saving starts on the second Sunday in March and ends on the first Sunday in November. Households in Hawaii feel both changes, even though their own clocks stay put. These are the upcoming dates when every mainland gap shifts by an hour:

• March 8, 2026: gaps widened to 3 hours (Pacific) and 6 hours (Eastern)
• November 1, 2026: gaps narrow to 2 hours (Pacific) and 5 hours (Eastern)
• March 14, 2027: gaps widen again
• November 7, 2027: gaps narrow again

The mainland switch happens at 2:00 am local time, which is Saturday evening in Hawaii. For East Coast contacts, the March change takes effect at 9:00 pm HST Saturday and the November change at 8:00 pm HST Saturday. Recurring calendar invites created in a mainland zone will jump an hour on the Hawaii side that weekend.

Remote work on Hawaii time

For relocating professionals, the time zone matters most on workdays. A mainland employer’s 9-to-5 lands very early in the Hawaii morning, and the effect grows the farther east the employer sits. The table below converts a standard mainland workday into HST and shows how many hours overlap with a 9 am to 5 pm Hawaii day.

The 6 am start for East Coast jobs

A strict 9:00 am Eastern start means logging on at 3:00 am HST from March to November. Few people can keep that up. The usual compromise is a 6:00 am HST start, which lands at 11:00 am Eastern in winter and noon Eastern in summer, covering the busiest part of the Eastern afternoon.

A 6:00 am to 2:00 pm HST shift overlaps Eastern business hours for 6 hours in winter (11 am–5 pm EST) and 5 hours in summer (noon–5 pm EDT). Workers give up the Eastern morning and get their afternoons back. Many describe being done by 2:00 or 2:30 pm, with daylight left for the beach or errands.

The friction comes from morning meetings. A 9:30 am Eastern all-hands is 3:30 am HST in summer. Teams that hire Hawaii-based staff often move standing meetings to after 11:00 am Eastern or record them. The site’s remote work from Hawaii guide covers how employees handle that conversation and which roles fit the schedule.

West Coast and Central employers

West Coast jobs are the easiest fit. A 9:00 am Pacific start is 7:00 am HST in winter and 6:00 am HST in summer, which is early but workable. Central-time employers fall in between. A 9:00 am Central start means 5:00 am HST in winter and 4:00 am in summer, so a later-shifted schedule is usually needed there too.

Taxes do not follow the employer’s clock

Working on mainland hours does not mean being taxed as a mainland worker. Hawaii residents generally owe Hawaii income tax on wages earned while physically working in the state, whatever the employer’s location. The breakdown of Hawaii remote work taxes for 2026 explains the rules, and the Hawaii Department of Taxation publishes current rates and forms.

Markets, deadlines and customer service lines

Many fixed national events are set in Eastern time, and they arrive very early in Hawaii. The New York Stock Exchange opens at 9:30 am Eastern, which is 3:30 am HST in summer and 4:30 am HST in winter. The closing bell at 4:00 pm Eastern rings at 10:00 am or 11:00 am HST.

Customer service lines are a common surprise. A bank, insurer or airline call center that closes at 8:00 pm Eastern stops answering at 2:00 pm HST in summer and 3:00 pm in winter. Online portals with Eastern-time deadlines, such as 11:59 pm ET, effectively close at 5:59 pm or 6:59 pm in Hawaii.

Call windows with family and friends on the mainland

Social calls are the other everyday adjustment. The Eastern evening, when most mainland families are free, falls in the Hawaii afternoon, while many new arrivals are still at work. The useful windows are narrower than people expect. The table shows common Hawaii times and what they mean on each coast.

Weekends are easier. A 9:00 am Saturday call from Hawaii reaches the East Coast at 2:00 or 3:00 pm and the West Coast at 11:00 am or noon, so it suits everyone. Many relocated families set a standing weekend-morning video call for that reason, since weekday windows close so early.

Messages that come in overnight are part of the routine. A sibling texting at 7:00 am Eastern wakes a Hawaii phone at 1:00 or 2:00 am. New residents often set a scheduled Do Not Disturb from about 9:00 pm to 6:00 am HST, with exceptions for a few emergency contacts.

Live TV, sports and big events

National broadcasts run on Eastern schedules, so Hawaii viewers watch them during the day. During fall daylight saving, a 1:00 pm Eastern NFL Sunday kickoff starts at 7:00 am HST. After the November switch it moves to 8:00 am. Monday Night Football at 8:15 pm Eastern airs at 2:15 or 3:15 pm HST.

Some annual moments follow the same pattern. The Times Square ball drop happens at 7:00 pm HST on December 31, five hours before Hawaii’s own midnight. On federal election nights, the first Eastern polls close at 7:00 pm EST, which is 2:00 pm HST. Results often look settled before Hawaii voters finish dinner.

Red-eye flights home and the eastbound time penalty

Flying from Hawaii to the mainland means crossing 2 to 6 hours of clock time in the “losing” direction. Even a 5-hour flight eats a whole evening. That is why so many departures are scheduled as red-eyes: leave Hawaii in the evening and land on the mainland in time for breakfast. The time change makes the night aboard short.

Eastbound flights are usually faster than westbound ones because of prevailing jet-stream tailwinds, often by 30 to 60 minutes on West Coast routes. The schedules below are illustrative, built from typical block times. They show how one departure time lands differently in summer and winter.

The table shows a pattern. In winter, the same red-eye arrives an hour earlier by the mainland clock, sometimes before 6:00 am, when connecting flights, coffee shops and ground transport are thin. A summer red-eye lands closer to normal morning hours. Travelers with tight connections often favor the later winter arrivals for that reason.

Planning the last day before a red-eye

A 10:00 pm departure leaves a long final day. Most hotels and rentals check out at 10:00 or 11:00 am, which leaves about 11 hours to fill. Visitors on Maui face a version of this, covered in the Kahului red-eye rental return strategy. It explains when to drop the car and where to wait.

Price is the other factor. Red-eyes are not always the cheapest seats, and fares move with season and demand. The analysis of fare drop windows for Hawaii flights from the mainland covers when prices tend to soften. Airport information for all state-run airports is on the Hawaii Department of Transportation site.

Westbound: gaining the hours back

Flying to Hawaii works the other way. A flight leaving Los Angeles at 8:00 am PDT takes about 6 hours and lands in Honolulu around 11:00 am HST. An East Coast traveler leaving New York at 9:00 am EDT on a nonstop of about 11 hours lands around 2:00 pm HST, the same afternoon.

That gain in clock time is one reason Hawaii feels close despite the distance. Compared with Caribbean trips, Hawaii is a longer flight with a much bigger time change for East Coast residents. The comparison of flight hours between Hawaii and the Caribbean lays out the tradeoff.

Arrival day timing: landing in Hawaii

Most mainland flights reach Hawaii between late morning and early evening. A traveler’s body clock is still set to home time, and that matters. An East Coast arrival at 2:00 pm HST feels like 8:00 pm, and the traveler has likely been up since before dawn. Arrival-day plans work best when they stay simple.

Rental cars and the first few hours

Most arriving travelers start at the rental car counter. Several wide-body arrivals often land within the same hour at Honolulu and Kahului, so midday lines can be long. Booking ahead and joining a loyalty program that skips the counter cuts the wait. The guide to Hawaii rental car prices by island and season covers rates and airport fees.

The common hotel check-in time of 3:00 or 4:00 pm can leave a short gap after an 11:00 am landing. Using that time for groceries, a pharmacy run or a phone SIM setup is a practical way to stay awake. Long drives on unfamiliar roads after a 10-hour travel day carry more risk.

Moving-day logistics across time zones

Households relocating for good deal with more than one clock. Movers, the vehicle shipper and the old utility companies all keep mainland hours, while the new landlord and Hawaii utilities keep HST. Carriers such as Matson publish sailing schedules, and the West Coast to Honolulu ocean leg runs roughly a week.

A practical approach is to handle all mainland phone calls before 11:00 am HST, while both sides are open, and save local appointments for the afternoon. The total cost of moving to Hawaii covers the shipping, flight and pet budgets that this scheduling feeds into.

Booking windows that open on Hawaii time

Some reservations that are hard to get open on Hawaii time, which catches mainland planners off guard. Haleakala sunrise permits on recreation.gov are released 60 days ahead at 7:00 am HST, with a second batch 2 days ahead. That is 10:00 am Pacific and 1:00 pm Eastern during daylight saving.

Diamond Head and Haena State Park entries also use advance windows tied to HST. The overview of Hawaii parks that need reservations lists each system. Jet lag can help here. A newly arrived East Coast traveler who wakes at 4:00 am HST has no trouble making a sunrise permit that starts before 6:00 am.

Jet lag in both directions

Jet lag comes from the body clock running out of sync with local daylight. A commonly cited rule of thumb is that full adjustment takes about one day per time zone crossed. By that measure, an East Coast household arriving in Hawaii in summer faces a 6-hour shift and close to a week of partial adjustment.

Westbound arrival is usually easier

Flying west lengthens the travel day, and most people find it easier to stay up later than to fall asleep earlier. Travelers to Hawaii typically report waking at 3:00 or 4:00 am HST for the first several days, with a heavy slump in the late afternoon. Bright morning light and staying up until 8:00 or 9:00 pm local time speed the shift.

Eastbound return is usually harder

The trip home compresses the night. A red-eye that leaves at 10:00 pm HST and lands at 6:15 am Eastern-adjusted time leaves room for about 4 or 5 hours of broken sleep at most. The body then has to move its clock earlier, which most people find harder than moving it later.

Relocated residents who fly back to the mainland for work often plan a light first day after an eastbound red-eye. A short afternoon nap of under 30 minutes and an early bedtime in the new zone are common approaches. Anyone thinking about sleep aids or melatonin should ask a physician first.

Common adjustment strategies

• Shift bedtime 30 to 60 minutes toward the destination zone for 2 to 3 nights before departure.
• Get outdoor daylight in the first morning hours after arriving in Hawaii.
• Avoid naps longer than 30 minutes on arrival day.
• Keep caffeine to the morning and early afternoon in the new time zone.
• Drink water through the flight; cabin air is very dry on 5- to 11-hour legs.
• Schedule demanding meetings for the third day after arrival, not the first.

Sunrise, sunset and the daily rhythm of a no-DST state

Without daylight saving, Hawaii’s evenings stay short even in midsummer. Honolulu’s latest sunsets come in late June and early July at about 7:15 to 7:20 pm. Its earliest come in late November and early December at about 5:50 pm. Meanwhile Seattle’s June sunsets come after 9:00 pm under daylight time.

Daily life runs early to match. Many residents start the day before 6:00 am to surf, run or beat traffic, and commuter congestion on Oahu’s H-1 freeway builds well before 6:30 am on weekdays. Restaurants, especially outside Waikiki, often close earlier than mainland diners expect, with many neighborhood kitchens done by 9:00 pm.

The steady sunsets also take one transition off the calendar. Hawaii households never lose an hour of sleep in March, and children’s bedtimes never need resetting in November. The state tourism site, GoHawaii, lists island events in local time all year. The look at summer in Hawaii covers how heat and trade winds shape those evening hours.

How Hawaii time compares with other places that skip daylight saving

Hawaii is one of several U.S. jurisdictions that keep standard time all year. The others are useful reference points for households with ties elsewhere, especially military families and anyone with business in the Pacific territories. Several of these places sit an entire day away by the calendar.

• Arizona (excluding the Navajo Nation): UTC-7, always 3 hours ahead of Hawaii.
• Puerto Rico and the U.S. Virgin Islands: UTC-4, always 6 hours ahead of Hawaii.
• American Samoa: UTC-11, always 1 hour behind Hawaii.
• Guam and the Northern Mariana Islands: UTC+10, 20 hours ahead, so usually the next calendar day.

Guam is the odd case. At 8:00 am Monday in Honolulu, it is already 4:00 am Tuesday in Guam. Households with family on bases there, or business contacts in Japan and Australia, find their Asia-Pacific calls easier from Hawaii than from anywhere on the mainland. That is a real advantage for some careers.

A practical time-zone checklist for new Hawaii residents

Most of the friction described above can be handled with a few settings and habits in the first week. Relocation forums and employer onboarding guides tend to give the same advice. These are the steps that come up most often:

1. Set every calendar’s default zone to Pacific/Honolulu, not “Hawaii-Aleutian with DST.”
2. Add a second clock showing the employer’s zone on laptop and phone.
3. Put “Hawaii time (HST, UTC-10)” in email signatures and scheduling links.
4. Send meeting invites in the organizer’s zone and let software convert them.
5. Mark the March and November switch weekends on the calendar each year.
6. Make mainland bank, insurance and pharmacy calls before 11:00 am HST.
7. Check online deadlines for Eastern-time cutoffs that close at 5:59 or 6:59 pm HST.
8. Agree on a standing weekend call time with mainland family.

Frequently asked questions

What time zone is Hawaii in?

Hawaii uses Hawaii-Aleutian Standard Time (HST), 10 hours behind Coordinated Universal Time (UTC-10). Device settings usually list it as Pacific/Honolulu. The state stays on this offset all year because it does not observe daylight saving time, so its clocks never change in March or November.

Does Hawaii change its clocks for daylight saving time?

No. Hawaii opted out of daylight saving in 1967 under an exemption in the federal Uniform Time Act of 1966. Because Honolulu sits near 21°N, day length varies only about 2.5 hours across the year, so shifting the clock would add little useful evening daylight.

How many hours behind New York is Hawaii?

Hawaii is 5 hours behind New York from early November to mid-March and 6 hours behind during mainland daylight saving time. In 2026 the gap narrows to 5 hours on November 1. It widens to 6 hours again on March 14, 2027.

How many hours behind California is Hawaii?

Hawaii is 2 hours behind California in winter and 3 hours behind from the second Sunday in March to the first Sunday in November. Noon in Honolulu is 2:00 pm in Los Angeles in January and 3:00 pm in July.

Do all the Hawaiian islands share the same time?

Yes. Oahu, Maui, the Big Island, Kauai, Molokai and Lanai all run on HST with no differences between islands. Travelers on interisland flights, which usually take 30 to 50 minutes in the air, never need to adjust a watch or phone.

What time should a remote worker in Hawaii start for an East Coast job?

A strict 9:00 am Eastern start means 3:00 am HST in summer and 4:00 am in winter. Many Hawaii-based remote workers negotiate a 6:00 am HST start instead. That overlaps Eastern business hours for about 5 hours in summer and 6 hours in winter.

Is jet lag worse flying to Hawaii or flying home?

Most travelers find the trip home harder. Flying west to Hawaii lengthens the day, which the body handles fairly well. Eastbound red-eyes cut the night short and force the body clock earlier, so recovery after landing on the mainland usually takes longer.

Why do Hawaii red-eye flights land so early on the mainland?

Eastbound flights lose 2 to 6 hours of clock time as well as the flying time. A 10:00 pm departure from Honolulu on a 5-hour-15-minute flight reaches Los Angeles at 6:15 am in summer and 5:15 am in winter, when the mainland gap is one hour smaller.
