What is a Blue Moon?

A Blue Moon is often misunderstood due to its intriguing name. The term “Blue Moon” can refer to either the second full moon in a single calendar month or the third full moon in a season that has four full moons. While it might sound exotic, there is nothing inherently blue about this moon.

The Science Behind Blue Moons

The phenomenon of a Blue Moon is deeply rooted in the lunar cycle. The average lunar cycle is approximately 29.5 days, which means most months experience just one full moon. However, occasionally there isn’t enough time between full moons to fit them both in one month, especially in months with 31 days. This alignment results in a Blue Moon:

Occurs once every 2.5 to 3 years.
Not visibly blue; any blue hue is caused by atmospheric conditions such as dust or smoke particles.
