About time in Cheyenne
Cheyenne, Wyoming's capital and the seat of Laramie County, occupies the state's southeastern corner near the Colorado and Nebraska lines; Wyoming is a single-zone Mountain Time state.
The city was born of railroad time: Union Pacific crews platted Cheyenne in 1867 as the transcontinental line advanced across the plains, and it boomed to several thousand residents within months. Crossing into Nebraska's panhandle today changes nothing on the clock — Mountain Time continues past Scottsbluff.
June daylight tops 15 hours here, and the 2026 daylight-saving stretch runs from March 8 to November 1; December days hold a bit over 9 hours of sun.
