Idaho Usa Time Zones Explained

Idaho, located in the northwestern United States, observes two time zones: Pacific Time Zone (UTC-8) and Mountain Time Zone (UTC-7). The state's unique geography, with its panhandle region situated near the Canadian border and its southern areas bordering Nevada and Utah, contributes to this dual time zone setup. Understanding the time zones in Idaho is essential for residents, visitors, and businesses to coordinate activities, communicate effectively, and navigate the state's diverse regions.
Time Zone Boundaries in Idaho

The time zone boundary in Idaho runs along the western edge of the panhandle, separating the Pacific Time Zone from the Mountain Time Zone. The specific boundary follows the Idaho- Oregon border to the southern tip of the panhandle, then turns east to follow the Salmon River, and finally turns south to follow the Bitterroot Mountains. This boundary effectively divides the state into two time zones, with the northern panhandle observing Pacific Time and the rest of the state observing Mountain Time.
Pacific Time Zone in Idaho
The Pacific Time Zone, also known as UTC-8, is observed in the northern panhandle of Idaho, including the cities of Coeur d’Alene, Sandpoint, and Bonners Ferry. This region is closely tied to the Pacific Northwest, both culturally and economically, and shares a border with the Canadian province of British Columbia. During standard time, the Pacific Time Zone is 1 hour behind the Mountain Time Zone, and during daylight saving time, it is 1 hour behind the Mountain Time Zone as well.
Mountain Time Zone in Idaho
The Mountain Time Zone, also known as UTC-7, is observed in the majority of Idaho, including the capital city of Boise, as well as major cities like Idaho Falls, Pocatello, and Twin Falls. This region is closely tied to the Rocky Mountains and the western United States, both culturally and economically. During standard time, the Mountain Time Zone is 1 hour ahead of the Pacific Time Zone, and during daylight saving time, it is 1 hour ahead of the Pacific Time Zone as well.
Time Zone | Cities | UTC Offset |
---|---|---|
Pacific Time Zone | Coeur d'Alene, Sandpoint, Bonners Ferry | UTC-8 |
Mountain Time Zone | Boise, Idaho Falls, Pocatello, Twin Falls | UTC-7 |

Implications of Idaho’s Time Zones

The dual time zone setup in Idaho has significant implications for various aspects of life and business in the state. For instance, communication and coordination between different regions of the state can be challenging, especially during daylight saving time. Additionally, the time zone difference can affect trade and commerce, as well as tourism and transportation. However, the unique time zone setup also presents opportunities for Idaho to leverage its strategic location and cultural ties to both the Pacific Northwest and the Rocky Mountains.
Economic Implications
The time zone difference in Idaho can have economic implications, particularly in terms of trade and commerce. Businesses operating in both the Pacific and Mountain Time Zones must navigate the time difference to coordinate activities, manage supply chains, and communicate with clients and partners. However, the dual time zone setup can also provide opportunities for businesses to expand their markets and reach new customers in different regions.
Social Implications
The time zone difference in Idaho can also have social implications, particularly in terms of cultural and social activities. For instance, the Pacific Time Zone region in the panhandle may have closer cultural ties to the Pacific Northwest, while the Mountain Time Zone region may have closer ties to the Rocky Mountains. This can lead to unique cultural and social dynamics, with different regions of the state developing distinct identities and traditions.
