🔵 Fun Blue Moon Facts
A Blue Moon happens when there are two full moons in one month
It occurs only every 2–3 years, which is why we say “once in a blue moon”
The moon isn’t actually blue — but the moment is still rare and special
This is one of those runs people remember and say: “I was there for that.”
