Frequently Asked Questions
What is the time difference between HST and GST?
During standard time, Gulf Standard Time is 14 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.
Does Dubai use Daylight Saving Time?
Dubai and the entire United Arab Emirates do not observe Daylight Saving Time, remaining fixed at UTC+4:00 throughout the year. This means the offset between Dubai and DST-observing countries such as the UK or the US shifts by one hour each spring and autumn when those countries change their clocks.
Is GST the same as UAE Standard Time?
Yes, UAE Standard Time is the national designation for the same UTC+4:00 offset that Gulf Standard Time describes regionally. Both terms refer to the same fixed clock used across the United Arab Emirates, and GST additionally covers Oman under its regional name.
