What time zone is Idaho?

Idaho primarily falls within the Mountain Time Zone (MT), which is UTC-7:00 during Standard Time and UTC-6:00 during Daylight Saving Time. However, some areas in northern Idaho observe the Pacific Time Zone (PT), which is UTC-8:00 during Standard Time and UTC-7:00 during Daylight Saving Time. The specific time zone depends on the region's proximity to neighboring states.

Note that the start and end dates of daylight saving time can change


Idaho's area codes include the long-standing 208, established in 1947, covering the entire state. In 2017, the overlay code 986 was introduced to meet growing demand for phone numbers. This dual-code system ensures a sufficient supply of numbers while preserving the 208 code's familiarity.
