Honolulu is 5 hours behind Miami in winter, 6 in summer
Miami switches clocks. Hawaii does not. That single fact controls every calculation.
During Eastern Standard Time, Honolulu runs 5 hours behind Miami. During Eastern Daylight Time, the gap widens to 6 hours. The split happens on two specific Sundays each year, and the rest of the calendar follows from there.
| Miami period | Honolulu offset | Example (Miami 3:00 PM) |
|---|---|---|
| EST (early November to mid-March) | 5 hours behind | 10:00 AM in Honolulu |
| EDT (mid-March to early November) | 6 hours behind | 9:00 AM in Honolulu |
What time is it in Honolulu when Miami is on EST?
From the first Sunday in November until the second Sunday in March, Miami runs on Eastern Standard Time (UTC−5). Honolulu stays on Hawaii Standard Time (UTC−10) all year.
Subtract 5 hours from Miami time. A 3:00 PM January call in Miami reaches Honolulu at 10:00 AM. That window gives you a solid morning block for business calls originating from the East Coast.
What time is it in Honolulu when Miami is on EDT?
On the second Sunday in March, Miami springs forward to Eastern Daylight Time (UTC−4). The difference jumps to 6 hours. Honolulu does not move.
From March to November, a 3:00 PM Miami call lands at 9:00 AM in Honolulu. You lose one hour of overlap compared to the winter schedule. Book Miami calls before 2:00 PM to keep them inside the Hawaii business morning.
Why the Miami, Honolulu time difference changes
Hawaii opted out of daylight saving time under the Uniform Time Act and has not observed DST since 1967. Honolulu stays on Hawaii Standard Time (UTC−10) permanently. The IANA zone is Pacific/Honolulu.
Miami follows America/New_York, cycling between UTC−5 (EST) and UTC−4 (EDT). The shift happens at 2:00 AM local on the second Sunday of March (spring forward) and the first Sunday of November (fall back). Hawaii’s clock never moves, so the gap between the two cities expands and contracts by one hour twice a year.
Best times to call from Miami to Honolulu
Schedule Miami calls between 12:00 PM and 3:00 PM. That lands in Honolulu between 7:00 AM and 10:00 AM during EST, or 6:00 AM and 9:00 AM during EDT.
During EST (November to March): dial at 12:00 PM Miami time. Honolulu picks up at 7:00 AM. You get a clean 3-hour window before the Hawaii lunch break.
During EDT (March to November): wait until 1:00 PM or 2:00 PM Miami time. That hits Honolulu at 7:00 AM or 8:00 AM. A 12:00 PM call arrives at 6:00 AM. Too early.
Skip Miami evenings for business calls. A 7:00 PM Miami call reaches Honolulu at 2:00 PM EST or 1:00 PM EDT. The Hawaii workday is already winding down.
Best times to call from Honolulu to Miami

Check the live converter on transition Sundays
The two transition Sundays break the standard rule. On the second Sunday of March, Miami jumps forward at 2:00 AM local. That Sunday, Miami and Honolulu are 5 hours apart in the early morning and 6 hours apart for the rest of the day. On the first Sunday of November, the reverse happens: 6 hours early, then 5 hours after Miami falls back.
Anyone booking a flight or a cruise connection between Miami and Hawaii on those weekends must check local departure and arrival times directly. A one-hour shift can turn an 8:00 AM connection into a 7:00 AM connection you miss.
For every other day of the year: summer means 6 hours, winter means 5 hours. Hawaii never changes.
