What these numbers mean
Sunset is only the start. Faint stars, the Milky Way and meteor showers need astronomical darkness — the sun more than 18° below the horizon. Between sunset and that point the sky is still washed out by twilight. The moon matters just as much: a full moon can wipe out three magnitudes of faint detail even in a cloudless sky, so the number that actually decides your night is how many hours are dark and moon-free at the same time. That is what this page computes for Reykjavík, from scratch, for the exact date shown.
What this page does not tell you These are astronomical figures only. Cloud cover, haze and local light pollution are not included and can override everything above. The app adds a live cloud forecast on top of these numbers.
