Time in Alaska (Russian: время в Аляске, vremya v Alyaske) is divided between three official time zones which span across the 18 governorates of the Alaskan Democratic Federative Republic. Two additional time zones are unofficially used in the easternmost and westernmost portions of Alaska. For practical purposes, all of Alaska's time zones are kept in sync with those of Borealia, Mexico, and the United States. Despite their cultural and historic connections, Alaska is currently a day behind the Russian Federation (divided by the International Date Line).
