When the difference changes

Hawaii Standard Time and Eastern Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 13, 2027Eastern Time is 5 hours ahead
  2. March 13, 2027 – November 6, 2027Eastern Time is 6 hours ahead
  3. November 6, 2027 – onwardsEastern Time is 5 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Hawaii Standard Time

No clock changes

Hawaii Standard Time stays on HST all year, so its offset from UTC never moves.

Scheduling between the two

Working hours overlap from 9:00 am to 1:00 pm HST, which is 2:00 pm to 6:00 pm EST. Anything inside that window falls in the normal working day at both ends.

Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving

Eastern Time (EST) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast
