Time Difference Between Boise and Pacific Time Zones

Boise, Idaho, is located in the Mountain Time Zone, placing it one hour ahead of the Pacific Time Zone. This one-hour difference remains consistent year-round because both regions observe Daylight Saving Time on the same schedule.

Updated with grounded research as of 2026-10-16.

The short answer

Boise, Idaho, resides within the Mountain Time Zone. Consequently, it is consistently one hour ahead of the Pacific Time Zone. Because both zones transition into and out of Daylight Saving Time on the same dates, this one-hour offset remains constant throughout the entire year, regardless of the season.

Key facts

Time Zone Relationship
Boise operates on Mountain Time (MT), which is one hour ahead of Pacific Time (PT).
Seasonal Consistency
The one-hour difference is stable year-round because both regions follow the same schedule for Daylight Saving Time transitions.

Understanding Idaho's Time Zones

While Boise falls entirely within the Mountain Time Zone, it is important for residents and visitors to be aware that Idaho is unique in that it is split between two time zones. Understanding where you are planning to travel or relocate within the state is essential for scheduling and logistics.

  • Boise and Southern/Central Idaho: Mountain Time Zone
  • Northern Idaho (The Panhandle): Pacific Time Zone

Daylight Saving Time Stability

You do not need to worry about the time gap changing throughout the year. Both the Mountain and Pacific Time zones adhere to the federal schedule for Daylight Saving Time. As a result, the transition from Mountain Standard Time (MST) to Mountain Daylight Time (MDT) occurs simultaneously with the shift in the Pacific zone, preserving the one-hour difference.

As of October 16, 2026, Boise is currently observing Mountain Daylight Time (MDT).

Planning Across Time Zones

When coordinating meetings, travel, or real estate appointments across the state line or within Idaho's dual-zone geography, always confirm the specific time zone of your destination. If you are communicating with partners in the Pacific Time Zone (such as those in Seattle, Portland, or Northern Idaho), remember that their clock will always be sixty minutes behind yours in Boise.

Common questions

Does all of Idaho use the same time zone?

No. Most of Idaho, including Boise and the southern region, uses Mountain Time. However, the northern portion of the state, known as the Idaho Panhandle (roughly north of the Salmon River), observes Pacific Time.

When does the time difference change during the year?

The time difference does not change. Because both Mountain and Pacific Time zones follow the same Daylight Saving Time start and end dates, the one-hour offset remains constant year-round.

If it is 12:00 PM in Boise, what time is it in Northern Idaho?

If it is 12:00 PM in Boise (Mountain Time), it is 11:00 AM in Northern Idaho (Pacific Time).
