Why sunset time shifts in Grundy Center

Sunset drifts through the year with Earth’s ~23.4° axial tilt — see the full daylight explainer.

In Grundy Center, the longest day carries about 15h 17m of daylight and the shortest just 9h 4m — a swing of roughly 6h 13m between the June and December solstices. The farther a place sits from the equator, the wider that gap; the pace also isn’t steady, moving fastest near the equinoxes and barely at all near the solstices.
