Which time zone is Hawaii in relative to Coordinated Universal Time?

Hawaii operates on Hawaii-Aleutian Standard Time (HAST), which is 10 hours behind Coordinated Universal Time (UTC). This time zone is specific to areas in Hawaii and the Aleutian Islands in Alaska, particularly during the standard time period when daylight saving is not in effect.

Unlike many other regions in the United States, Hawaii does not observe daylight saving time, remaining consistent with HAST throughout the year. This means that the time difference relative to UTC remains stable at 10 hours behind. Clock adjustments or shifts that typically occur in regions that observe daylight saving do not apply to Hawaii, making it unique in its timekeeping.

In contrast, the other options reference different time zones that do have variable time offsets from UTC and do not apply to Hawaii. Understanding these distinctions is crucial for travelers or anyone dealing with scheduling and planning in relation to Hawaii's time zone.
