Hawaii runs on Hawaii Standard Time (HST), which is UTC-10 — 10 hours behind Greenwich Mean Time. Unlike most of the mainland United States, Hawaii does not observe Daylight Saving Time. Clocks never spring forward or fall back. The time stays the same 365 days a year.
That consistency makes planning easy, but the gap between Hawaii and the mainland shifts twice a year when the rest of the country changes clocks. The tables below show the current time in every major zone and how the offset changes by season.
Time in Hawaii vs Other Time Zones
This table updates automatically with the current time in each zone. The "vs Hawaii" column shows how many hours ahead (+) or behind (-) each location is compared to Hawaii right now.
All times update in real time. Offsets change when mainland zones switch to/from Daylight Saving Time.
Does Hawaii Observe Daylight Saving Time?
No. Hawaii has never observed Daylight Saving Time in its modern history. The state opted out under the Uniform Time Act of 1966, which gave states the right to exempt themselves. Hawaii and Arizona are the only two US states that do not participate in DST.
The reason is geography. Hawaii sits near the equator (roughly 20°N latitude), so day length barely changes between summer and winter — sunrise and sunset shift by less than 90 minutes across the entire year. Adjusting clocks would gain almost nothing.
For travelers, this means the time difference between Hawaii and the mainland changes twice a year — not because Hawaii moves, but because the mainland does. The offset is one hour wider during Daylight Saving months (March through November) than during Standard Time months.
Hawaii Time Difference by Season
Because Hawaii stays on HST year-round while the mainland switches clocks, the gap between Hawaii and every other US time zone shifts by one hour in March and November.
| Mainland Zone | DST Gap (Mar–Nov) | Standard Gap (Nov–Mar) |
|---|---|---|
| Pacific (CA, OR, WA, NV) | Hawaii is 3 hrs behind | Hawaii is 2 hrs behind |
| Mountain (CO, AZ*, UT, NM) | Hawaii is 4 hrs behind | Hawaii is 3 hrs behind |
| Central (TX, IL, MN, WI) | Hawaii is 5 hrs behind | Hawaii is 4 hrs behind |
| Eastern (NY, FL, GA, MA) | Hawaii is 6 hrs behind | Hawaii is 5 hrs behind |
*Arizona also does not observe DST, so the Hawaii–Arizona gap stays at 3 hours year-round.
Planning Around the Time Difference
The time gap between Hawaii and the mainland catches more travelers off guard than you would expect. Here is how to make it work for you instead of against you.
Jet Lag
Flying west to Hawaii is generally easier on the body than flying east. Most mainland travelers lose 3–6 hours, which means your body thinks it is late afternoon when Hawaii says it is lunchtime. Expect to wake up early the first two mornings — use that to your advantage by booking sunrise hikes, early snorkel trips, or farmers market visits while you are naturally alert.
Going home is harder. You will feel the lost hours when your alarm goes off at 6 AM Eastern while your body insists it is midnight. Give yourself at least one recovery day before returning to work.
Booking Activities Across Time Zones
Calling Home
The biggest window for reaching family and coworkers on the mainland is mid-morning Hawaii time. At 10:00 AM HST during summer, it is 1:00 PM Pacific, 3:00 PM Central, and 4:00 PM Eastern — everyone is still awake and at work. By 6:00 PM HST, the East Coast is already at midnight.
Flight Timing
Flights from the West Coast to Hawaii typically depart in the morning and arrive in the early afternoon HST — you gain time flying west, so a 5-hour flight that leaves LA at 8:00 AM arrives around 11:00 AM Hawaii time. Return flights often leave in the afternoon HST and land late at night Pacific time, eating the entire evening.
Frequently Asked Questions
What timezone is Hawaii in?
Hawaii is in the Hawaii-Aleutian time zone and uses Hawaii Standard Time (HST), which is UTC-10. All major Hawaiian islands — Oahu, Maui, Kauai, and the Big Island — share the same time zone.
Does Hawaii observe Daylight Saving Time?
No. Hawaii does not observe Daylight Saving Time. The state opted out under the Uniform Time Act of 1966. Clocks in Hawaii never change — HST stays at UTC-10 all year.
What is the time difference between Hawaii and California?
Hawaii is 3 hours behind California during Daylight Saving Time (mid-March through early November) and 2 hours behind during Standard Time (November through mid-March). When it is noon in Hawaii during summer, it is 3:00 PM in California.
What is the time difference between Hawaii and New York?
Hawaii is 6 hours behind New York during Daylight Saving Time and 5 hours behind during Standard Time. When it is noon in Hawaii during summer, it is 6:00 PM in New York.
Why does Hawaii not observe Daylight Saving Time?
Hawaii sits near the equator (about 20°N latitude), so day length barely changes between summer and winter. Shifting clocks would gain less than an hour of usable daylight — not enough to justify the disruption. Hawaii and Arizona are the only US states that skip DST.
What time zone does the military use in Hawaii?
The US military in Hawaii uses the NATO phonetic designation "Whiskey" time (UTC-10), which is the same as HST. Military installations on Oahu (Pearl Harbor, Schofield Barracks, Hickam) all operate on HST.
