Clock Changes in Idaho: A Local Guide

Idaho observes Daylight Saving Time (DST) in alignment with federal standards across both the Mountain and Pacific time zones. Clocks adjust twice annually: 'springing forward' on the second Sunday in March and 'falling back' on the first Sunday in November.

Updated with grounded research as of 2026-11-09.

The short answer

Idaho observes Daylight Saving Time, requiring residents to adjust their clocks twice each year. Because the state is split between two time zones—Mountain Time and Pacific Time—the change affects residents differently depending on their location, though the schedule remains synchronized across both zones.

Understanding Idaho's Two Time Zones

Idaho is geographically divided into two separate time zones, a factor that is important for travelers, logistics, and planning across the state. The majority of the state, including Boise and the southern region, operates on Mountain Time. The northern region, known as the Idaho Panhandle, operates on Pacific Time.

  • Mountain Time Zone: Southern and Central Idaho.
  • Pacific Time Zone: North Idaho (Panhandle region).
  • Despite the difference in zones, both regions adhere to the same Daylight Saving Time schedule.

The Annual Schedule

The adjustment of clocks follows the standard federal mandate observed by most U.S. states. This ensures uniformity for business and transportation across state lines.

  • Spring Forward: Clocks move one hour ahead at 2:00 a.m. on the second Sunday of March.
  • Fall Back: Clocks move one hour behind at 2:00 a.m. on the first Sunday of November.
  • Effect: This transition results in longer daylight hours in the evening during summer months and earlier sunrises in the winter.

Impact on Daily Operations

For those relocating to or doing business in Idaho, it is helpful to remain aware of these transitions, especially when coordinating meetings or travel between the northern and southern parts of the state. While the time zones differ, the simultaneous clock changes simplify interstate and intrastate scheduling.

  • Travel planning: Crossing from Northern Idaho to Southern Idaho involves crossing a time zone boundary, resulting in a one-hour time gain or loss.
  • Scheduling: Always verify the local time zone when scheduling calls or appointments between Boise and Coeur d'Alene.

Common questions

Does Idaho plan to end Daylight Saving Time?

While there has been intermittent legislative discussion in various states regarding the permanent adoption of Standard or Daylight Saving Time, Idaho currently follows federal regulations. Any change to permanent Daylight Saving Time would require Congressional approval.

When does the next clock change occur?

The next clock change in Idaho will occur on Sunday, March 14, 2027, when clocks move forward one hour for the start of Daylight Saving Time.
