Montana's time zone
Montana observes Mountain Time across its entire 550-mile width: MST (UTC−7) in winter and MDT (UTC−6) in summer. The fourth-largest state keeps a single clock from Wibaux on the North Dakota line to the Idaho border.
The nearest zone change is to the west, where Idaho's northern panhandle runs on Pacific Time — crossing I-90 at Lookout Pass toward Coeur d'Alene sets watches back an hour. Montana's northern latitude also stretches its summer days: along the Hi-Line near the 48th parallel, late-June daylight lasts around 16 hours.
