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 South Dakota
The 3 South Dakota cities listed here span 1.9° of latitude, from Sioux Falls in the south (43.5°N) to Aberdeen in the north (45.5°N). On the June solstice that puts about 15h 41m of daylight over Aberdeen against 15h 26m over Sioux Falls — a 15m difference inside one state. In December the gap reverses, and the southern cities are the ones holding more light.
The median South Dakota city swings 6h 37m between the solstices against a national median of 5h 16m, so seasons here move the clock 1h 21m more than they do in a typical American city.
Seasons bite hardest in Aberdeen, where daylight swings 6h 58m between the solstices, and least in Sioux Falls at 6h 29m. The table above lists both figures for every city, so you can see where any town falls between those two extremes.
South Dakota spans more than one time zone (Central Time and Mountain Time), so two cities here can be on different clocks despite similar longitudes. Longitude decides how a city's clock lines up with its Sun: Aberdeen sits furthest west inside its zone, which puts mean solar noon about 34 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.
