Dusk in Jacksonville, stage by stage
Dusk in Jacksonville runs the same three stages as dawn, in reverse. Once the sun sets, civil dusk, the last usable light, lingers until the sun is 6 degrees below the horizon. Nautical dusk follows at 12 degrees, when the sea horizon disappears, and astronomical dusk at 18 degrees, after which the sky is fully dark and the faintest stars appear. How long dusk lasts depends on Jacksonville's latitude: near the equator night falls fast, while at high latitudes dusk can stretch for hours or, in high summer, never fully darken. Every time here is computed for Jacksonville's coordinates and shown in its local time zone.
