How we count
A night counts from the moment the Sun is 8° below the horizon (bright stars are visible) until it climbs back. An hour is clear when cloud cover is 30% or less. A night is clear when at least 3 of its dark hours are clear (or 60% of them on short summer nights). Past years come from the ERA5 weather archive via Open-Meteo, recent nights are added every day.
