Look up at the full moon tonight and you will see an extra special sight! It’s a blue moon! No, the moon will not actually be blue…but by definition, the full moon tonight classifies as a blue moon.
There are two definitions for a blue moon. The first, and most popular, is that a blue moon is the 2nd full moon in 1 month. However, there is a different definition that goes back even further. The 2nd definition states: when there are 4 full moons in 1 season, the 3rd full moon is called the blue moon.
Our full moon tonight will be the 3rd of 4 full moons this summer season making it the blue moon. Take a look:
Summer season: June 21st – September 22nd
1st full moon: Jun. 23rd
2nd full moon: Jul. 22nd
3rd full moon: Aug. 20th (BLUE MOON)
4th full moon: Sept. 19th
Something neat to see, and of course, these happen once in a blue moon.
