All Cities
Longest and shortest day are the June and December solstice day lengths at each city's own coordinates. Sun vs. clock is how far mean solar noon falls from 12:00 standard time — negative means the Sun peaks before the clock says noon.

Sunrise and Sunset in Wyoming
The 4 Wyoming cities listed here span 3.1° of latitude, from Cheyenne in the south (41.1°N) to Gillette in the north (44.3°N). On the June solstice that puts about 15h 31m of daylight over Gillette against 15h 9m over Cheyenne — a 23m difference inside one state. In December the gap reverses, and the southern cities are the ones holding more light.
The median Wyoming city swings 6h 9m between the solstices against a national median of 5h 16m, so seasons here move the clock 53m more than they do in a typical American city.
Seasons bite hardest in Gillette, where daylight swings 6h 40m between the solstices, and least in Cheyenne at 5h 56m. The table above lists both figures for every city, so you can see where any town falls between those two extremes.
Wyoming sits entirely in Mountain Time. Longitude decides how a city's clock lines up with its Sun: Casper sits furthest west inside its zone, which puts mean solar noon about 5 minutes after clock noon and gives it the state's latest-running evenings for its longitude.
Each city page carries that city's full profile: today's sunrise and sunset on a live tracker, a twelve-month table of times, the dates of the year's earliest and latest sunsets, the Sun's midday height by season, a golden-hour calendar, clear-sky solar-energy figures, and where the city ranks against the rest of the country.
