Frequently Asked Questions
What is the time difference between HST and EST?
During standard time, Eastern Standard Time is 5 hours ahead of Hawaii-Aleutian Standard Time.
Does Hawaii observe Daylight Saving Time?
Hawaii does not observe Daylight Saving Time and has not done so since 1947, remaining fixed at UTC-10:00 year-round. At roughly 20° North latitude, Hawaii's daylight hours vary by only about 1.5 hours between the summer and winter solstices — far too little to justify the disruption of a seasonal clock change.
Why is it called Hawaii-Aleutian time?
The name combines two geographically distant US territories that share the same UTC-10:00 standard offset: the Hawaiian Islands in the central Pacific and the westernmost Aleutian Islands of Alaska, which extend past the 180° meridian into the Eastern Hemisphere. Despite sharing a base offset, they behave differently — Hawaii observes no DST, while the Aleutian communities such as Adak do advance to HDT (UTC-9) each summer.
Is EST the same as Eastern Time (ET)?
Not exactly. 'Eastern Time' (ET) is a broad geographical term. EST is the specific UTC-05:00 offset used in winter, while EDT (Eastern Daylight Time) is the UTC-04:00 offset used during summer.
Does Florida use EST?
Most of Florida is in the Eastern Time Zone. However, the western part of the Florida Panhandle operates on Central Time (CST/CDT).
