Alaska time is one hour behind Pacific time and four hours behind Eastern time. Compare your time zone with Alaska time in the chart on this page.
Alaska time encompasses the entire state except for the Aleutian Islands west of Umnak Island, home of the village of Nikolski. You may find that point easily by drawing a line south from the Pribilof Islands.
Hawaii-Aleutian time -- the zone an hour behind Alaska Time -- includes the settlements of Atka, Adak, Attu and Shemya. (The Pribilofs are in Alaska Time.)
The state once boasted four time zones (Pacific, Yukon, Alaska and Bering zones), but they were compressed in 1967 into three and then again in 1983 into two as a way to improve business and communication.
The Alaska Panhandle was included in Pacific time, Yakutat was practically by itself in Yukon time, Alaska time covered the main chunk of Alaska westward from Canada to about 162 degrees west (north and south from Bethel), and Bering time included Nome, Kotzebue, Dutch Harbor/Unalaska and the Aleutians.
Alaska uses daylight saving time on the same schedule as most of the other states. DST begins on the first Sunday in April and ends on the last Sunday in October.
International Date Line
The International Date Line runs between Alaska and Russia. The line swings eastward off its 180 degree longitude baseline to split Little Diomede (U.S.) and Big Diomede (Russia) islands in the Bering Strait, then swings westward around Attu Island of the Aleutians.
When it's noon Monday in Anchorage, it's Tuesday morning in Siberia, Tokyo, Sydney and New Delhi. It's midnight in Moscow and Monday evening in Europe and Africa.
