The idiom "once in a blue moon" is used to describe an event that happens very rarely or infrequently. To use it in a sentence, you simply place it where you would indicate the frequency of an action.
Understanding the Idiom
The phrase "once in a blue moon" suggests an occurrence that is highly uncommon. While a "blue moon" actually refers to the second full moon in a single calendar month (a relatively rare celestial event), the idiom amplifies this rarity to describe anything that happens exceptionally seldom.
