Convert a specific time from HST to EST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between HST and EST?
Eastern Time is 6 hours ahead of Hawaii Standard Time. To go from HST to EST you add 6 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 5 hours to 6 hours, because Eastern moves its clocks and Hawaii does not. This page recomputes it rather than assuming.

Every hour of Wednesday, September 23, 2026 in Hawaii, with the matching reading in Eastern. 6 of the 24 hours land on a different calendar date in Eastern, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between HST and EST?
2 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 9:00 am HST to 11:00 am HST. In Eastern that window reads 3:00 pm to 5:00 pm. Outside it, one side is either not yet at their desk or already gone.
| HST | EST | Working hours | Note |
|---|---|---|---|
| 9:00 am | 3:00 pm | both sides | mid morning in Hawaii, afternoon in Eastern |
| 10:00 am | 4:00 pm | both sides | mid morning in Hawaii, afternoon in Eastern |
Does daylight saving change HST to EST?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
Eastern Time is currently on EDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-4 to UTC-5.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 5 hours and for the rest it is 6 hours. The table above is built for today, not for an average day.
Is HST ahead of or behind EST?
HST is behind EST by 6 hours: when it is 12:00 pm in Hawaii, it is 6:00 pm in Eastern. One wrinkle worth knowing: EST and EDT are two names for the same zone, not two zones. Eastern Time reads EST in winter and EDT in summer. When somebody types "hst to est" they nearly always mean the zone rather than the literal winter offset, so this page resolves HST to Pacific/Honolulu and EST to America/New_York and applies whichever offset is genuinely in force on the day.
Hawaii Standard Time covers Hawaii, which has never moved its clocks. Eastern Time covers New York, Toronto, Atlanta and Miami. The identifiers behind them are Pacific/Honolulu and America/New_York, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
