About time in Hilo
Hilo is the seat of Hawaii County, whose boundaries take in the whole Island of Hawaii — the Big Island — on the windward, rain-fed eastern coast facing Hilo Bay.
Because the state holds UTC−10 with no clock changes, Hilo's distance from the West Coast moves on the mainland's schedule alone: Los Angeles is two hours ahead here in winter and three ahead through the daylight saving months, even though nothing in Hilo ever changes.
On the slopes above town, the Mauna Kea summit hosts a cluster of major astronomical observatories where observing runs are commonly logged in Universal Time — a conversion that stays a constant ten hours all year precisely because HST never shifts.
Frequently asked questions
What time zone is Hilo in?
Hilo is on Hawaii Standard Time (HST, UTC−10) every day of the year. Like all of Hawaii, it never switches to daylight saving time.
What is the time difference between Hilo and New York?
New York is 5 hours ahead of Hilo during the mainland winter and 6 hours ahead from mid-March to early November, since Hawaii skips daylight saving time while New York observes it.
Does Hilo observe daylight saving time?
No. Hawaii keeps HST (UTC−10) year-round with no clock changes, so Hilo's offset to the mainland grows by an hour each March and shrinks back each November.
