blue moons & lunar eclipses 2025–2027 sky guide
A Blue Moon doesn’t look blue—it’s a name for a rare full moon event that comes in two forms:
- Monthly Blue Moon → The second full moon in a single calendar month.
- Seasonal Blue Moon → The third full moon in a season with four full moons instead of the usual three.
They only happen about once every two to three years, making them special for astronomers and casual skywatchers alike.
