What is 1 AM HST in EST?

Does the answer change during the year?

Yes. Hawaii Time and Eastern Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 1 AM HST = 7 AM EST
• November 1 to March 13: 1 AM HST = 6 AM EST
• March 14 to October 13: 1 AM HST = 7 AM EST

Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year.
