Alaska Standard and Daylight Time

Map of USA standard time zones, including Alaska
Standard time zones in the United States, including Alaska.

Alaska observes standard time at nine hours behind UTC (UTC-9), shifting to eight hours behind (UTC-8) during daylight saving time — one hour behind Pacific Time. Standard time in the zone is based on the mean solar time of the 135th meridian west of Greenwich. In the United States, it's generally called Alaska Time, specifically Alaska Standard Time (AKST) during winter and Alaska Daylight Time (AKDT) during daylight saving time. Since 2007, the shift from AKST to AKDT takes place at 2:00 a.m. on the second Sunday of March, and the shift back to AKST takes place at 2:00 a.m. on the first Sunday of November.

Alaska Is Divided Into Two Time Zones

Alaska's land area compared to the 48 contiguous U.S. states.

The western Aleutian Islands actually observe Hawaii-Aleutian Time, one hour behind the rest of the state. Alaska is the largest U.S. state by far — larger than all but 18 countries in the world, and about a fifth of the combined land area of the other 48 states. Its territory spans nearly as much longitude as the entire continental United States, so strictly by geography it would fall into four separate time zones; political considerations settled on two instead.

Daylight Saving Time in the USA and Canada

Daylight saving time begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November, in every USA and Canada time zone that observes it.

North American Time Zones

The same eight time zones from the comparison above, organized by UTC offset instead of by name — useful for seeing which zones share a clock time once daylight saving time shifts them.

GMT and UTC

Greenwich Mean Time (GMT) originally referred to mean solar time at the Royal Observatory in Greenwich, London. Coordinated Universal Time (UTC) is the modern, atomic-clock-based standard that has replaced it for precise timekeeping — but the two are close enough that they're used interchangeably in everyday contexts, including throughout this page.
