Idaho, located in the northwestern United States, observes a unique time zone arrangement. The state is divided into two time zones: Pacific Time Zone (UTC-8) and Mountain Time Zone (UTC-7). The majority of Idaho, including the capital city Boise, follows the Mountain Time Zone. However, the northern part of the state, which includes the cities of Coeur d'Alene and Sandpoint, observes the Pacific Time Zone.
Time Zone Overview

The Mountain Time Zone, which covers most of Idaho, is equivalent to UTC-7 hours during standard time and UTC-6 hours during daylight saving time. The Pacific Time Zone, observed in the northern part of the state, is equivalent to UTC-8 hours during standard time and UTC-7 hours during daylight saving time. It’s essential to note that Idaho does not observe daylight saving time in the same manner as some other states, as the entire state either observes standard time or daylight saving time uniformly.
Daylight Saving Time (DST) in Idaho
Idaho, like most states in the United States, observes daylight saving time. During the second Sunday in March, clocks “spring forward” by one hour, moving from standard time to daylight saving time. Then, on the first Sunday in November, clocks “fall back” by one hour, returning to standard time. This practice aims to make better use of natural daylight during the summer months, potentially conserving energy and promoting outdoor activities.
Time Zone | Standard Time | Daylight Saving Time |
---|---|---|
Mountain Time Zone | UTC-7 | UTC-6 |
Pacific Time Zone | UTC-8 | UTC-7 |

Key Points
- Idaho is divided into two time zones: Mountain Time Zone and Pacific Time Zone.
- The Mountain Time Zone covers most of the state, including Boise, and observes UTC-7 during standard time and UTC-6 during daylight saving time.
- The Pacific Time Zone is observed in the northern part of Idaho and follows UTC-8 during standard time and UTC-7 during daylight saving time.
- Idaho observes daylight saving time, with clocks changing in March and November.
- Understanding the time zones and daylight saving practices in Idaho is vital for coordinating activities across the state and with other regions.
Practical Implications of Time Zones in Idaho

The division of time zones in Idaho can have practical implications for residents and visitors alike. For instance, individuals traveling from the southern part of the state to the northern part must adjust their clocks accordingly to avoid missing appointments or schedule conflicts. Furthermore, businesses operating across these time zones must ensure that their operations are coordinated effectively to maintain productivity and customer satisfaction.
Economic and Social Impact
The observance of different time zones and daylight saving time can also have economic and social impacts on Idaho. The tourism industry, for example, may benefit from the extended daylight hours during the summer, as it can attract more visitors who enjoy outdoor activities such as hiking, fishing, and skiing. On the other hand, the energy-saving benefits of daylight saving time can contribute to a reduction in energy consumption, potentially leading to economic savings for residents and businesses.
In conclusion, the time zone arrangement in Idaho, although complex, plays a significant role in the daily lives of its residents and the operations of its businesses. Understanding these time zones and their implications is crucial for effective coordination and communication within the state and beyond.
