This EST to HST converter turns any time in Eastern Standard Time (EST) into Hawaii Standard Time (HST), using your device clock so daylight saving is applied automatically. HST is 5 hours behind EST when both zones are on standard time, and 6 hours behind during the summer months when clocks have shifted. EST is UTC−5 (EDT: UTC−4); HST is UTC−10.
EST covers New York, Toronto, Miami; HST covers Honolulu, Hilo. Because only EST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between EST and HST?
HST is 5 hours behind EST on standard time. During daylight saving the gap changes to 6 hours. That comes from the UTC offsets: EST is UTC−5 and HST is UTC−10. For example, 9 am EST = 4 am HST, and in summer 9 am EST = 3 am HST.
Is HST ahead of or behind EST?
HST is 5 hours behind EST, so when it is noon in EST it is 7 am in HST. Ahead means the clock there already shows a later time; a call at 5 pm EST lands at 12 pm HST.
Does EST or HST observe daylight saving time in 2026?
EST switches to EDT (UTC−4) on March 8 and back on November 1 in 2026. HST keeps UTC−10 all year. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between EST and HST?
Standard office hours (9 am to 5 pm) overlap from 2 pm to 5 pm EST, which is 9 am to 12 pm HST. Pick a slot inside that window and both sides stay within a normal working day. Check the daylight saving dates above, because the window moves by an hour when only one side has changed clocks.
Which cities use EST and HST?
EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. HST (Hawaii Standard Time) is used in Honolulu, Hilo. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
