Why sunset time shifts in Arecibo

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

In Arecibo, the longest day carries about 13h 14m of daylight and the shortest just 11h 1m — a swing of roughly 2h 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.
