Frequently Asked Questions
What is the time difference between PST and HST?
During standard time, Hawaii-Aleutian Standard Time is 2 hours behind Pacific Standard Time.
What is the difference between PST and PDT?
PST (Pacific Standard Time) is the winter offset at UTC-8, observed from the first Sunday in November through the second Sunday in March. PDT (Pacific Daylight Time) is the summer offset at UTC-7, active when Daylight Saving Time shifts clocks forward by one hour.
Which major cities observe Pacific Standard Time?
Major cities that observe Pacific Standard Time include Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver, and Tijuana.
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.
