Hawaii: Does the state observe daylight saving time?
Hawaii does not observe daylight saving time and stays on Hawaiian standard time all year.
A state law dating to 1947, last amended in 1967, requires the whole state, including every county, to keep Hawaiian standard time all year. It does this by opting out of the federal Uniform Time Act's clock change, which federal law allows. Bills to bring daylight saving time to Hawaii have been introduced over the years, but the law has not changed.
What the law says
Hawaiian standard time is ten hours slower than Greenwich time, based on the mean solar time of the one hundred and fiftieth degree of longitude west from Greenwich and shall be the time which the entire State, including all of its political subdivisions, shall observe annually, notwithstanding the daylight time conversion provisions of the Uniform Time Act of 1966, Public Law 89-387, 80 Statutes at Large 107.
