The idea
Idioms cannot be worked out word by word, but the image usually points the right way. Rarity is the whole idea of a blue moon.
Shortcut. A blue moon is the rare second full moon in one calendar month, roughly every two to three years — so the idiom means very rarely.
Common trap. "At night" — the literal reading: the moon appears at night, but the idiom is about rarity, not the time of day.
