Using Hawaii time for a trip?

Turn the time difference into a better first day.

If you are checking HST because you are planning calls, flights, tours, or arrival timing, these are the next useful steps.

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. HST stays at UTC-10 year-round.

The gap changes when a mainland location switches between standard time and daylight saving time. The live table shows the current offset; the seasonal table below explains how that offset changes. For a future booking, use the rule for that booking's date.

Time in Hawaii vs Other Time Zones

Compare the current time in the locations below. The "vs Hawaii" column shows how many hours ahead (+) or behind (-) each location is compared to Hawaii right now.

For a future booking, check the offset for that date. Offsets change when a location switches between standard time and daylight saving time.

Does Hawaii Observe Daylight Saving Time?

No. Hawaii stays on HST year-round. The NIST local-time guide lists Hawaii and most of Arizona among the places that do not observe daylight saving time; the Navajo Nation in Arizona does observe it.

A fixed time zone does not mean fixed sunrise and sunset times. Use our sunrise and sunset tool for the date and island of an outdoor plan.

For mainland locations that observe daylight saving time, the difference from Hawaii changes twice a year. The gap is one hour wider during daylight time than during standard time.

Hawaii Time Difference by Season

These four mainland cities observe daylight saving time. Their difference from Hawaii changes when their clocks switch; the table does not apply to places that stay on standard time.

Mainland Zone DST Gap (Mar–Nov) Standard Gap (Nov–Mar)
Pacific (Los Angeles) Hawaii is 3 hrs behind Hawaii is 2 hrs behind
Mountain (Denver) Hawaii is 4 hrs behind Hawaii is 3 hrs behind
Central (Chicago) Hawaii is 5 hrs behind Hawaii is 4 hrs behind
Eastern (New York) Hawaii is 6 hrs behind Hawaii is 5 hrs behind

Most of Arizona, including Phoenix, stays on Mountain Standard Time, three hours ahead of Hawaii year-round. The Navajo Nation observes daylight saving time. Check the specific location using the NIST local-time guide.

Planning Around the Time Difference

Use the date, location, and stated time zone together when planning a call, flight, or booking.

Arrival-Day Clock Change

Hawaii is two or three hours behind Los Angeles and five or six hours behind New York, depending on the date. Moving your clock backward does not add rest to a travel day. Use the local arrival time on your itinerary, and leave room to rest before a demanding outing.

The NIST daylight-saving guide lists the current change dates and Hawaii's exemption. Check the offset for your return date too; do not assume the difference stays the same throughout a trip that crosses a mainland clock change.

Booking Activities Across Time Zones

Check the stated time zone: Do not assume a booking or ticket deadline uses HST because the activity is in Hawaii. Read the time zone on the seller's official page and your confirmation. Keep the original date, time, and zone together, then convert for the date when you must act. If the zone is missing, ask the seller before setting a reminder.

A deadline, a check-in time, and a departure time are separate entries. Record each one. Our boat-tour backup-day guide shows how another booking's cancellation deadline can remove your fallback before a weather decision arrives.

Calling Home

Check the live table and agree on a time with the person you are calling. During daylight saving time, 10:00 a.m. HST is 1:00 p.m. in Los Angeles, 3:00 p.m. in Chicago, and 4:00 p.m. in New York. At 6:00 p.m. HST, New York has reached midnight the next day. During standard time, each of those mainland times is one hour earlier.

Flight Timing

Check both the departure and arrival dates and time zones on your airline itinerary. For a hypothetical five-hour flight leaving Los Angeles at 8:00 a.m., the arrival would be 10:00 a.m. HST when Los Angeles uses daylight time, or 11:00 a.m. HST when it uses standard time. Those are clock-conversion examples, not a flight schedule or a promised duration.
