Originally, Alaska had four time zones, but in the 1980s, the state reduced its number of time zones from four to two. In the present, part of the Aleutian Islands follows time which is an hour behind the rest of the state. The original four time zones were spanned in 1983, considered "one of the most comprehensive time zone changes in the last century" by the U.S. Department of Transportation.

During the time change, both Alaska's locals and tourists get confused about time. There were instances when students would have to walk to school in the dark each winter. But the good news is employees would enjoy more daylight at the end of their work. On October 30th of the same year, Anchorage and Fairbanks didn't change their clocks. This is because Daylight Saving Time was about to end, which required the residents to set their clocks back one hour.

It was reported that the majority of Alaska would transition to what was then called Yukon Time. It is the time zone that is an hour behind Pacific Standard Time. At present, a small area in the state observes its clock, Hawaii-Aleutian Standard Time. Meanwhile, Adak, an island west of, follows an hour behind the rest of the state. Thus, Alaska experienced many things when it comes to time zones during the two world wars. But what to know is that Alaska is officially in the Alaska Time Zone.
