Wyoming's time zone
Every corner of Wyoming keeps Mountain Time: MST (UTC−7) in winter and MDT (UTC−6) from the second Sunday of March to the first Sunday of November. Cheyenne in the southeast, Casper in the center, and Jackson by the Tetons never differ by a minute.
Yellowstone National Park, which spills over Wyoming's borders into Montana and Idaho, runs its published schedules on Mountain Time, and both neighboring states are Mountain on that side. The zone shifts only beyond Wyoming's western neighbors — central Idaho's Salmon River divide marks the change to Pacific — and to the east, where western Nebraska and western South Dakota stay Mountain before Central begins farther on.
