Rare Halloween Blue Moon | 2020

Saturday, October 31, 2020 - 7:00 pm to 4:00 am | Cost: FREE
San Francisco Bay Area |


The next Blue Moon will come on October 31, 2020. It’ll be called a Blue Moon because it’ll be the second of two full moons to occur in a single calendar month. The last Blue Moon by this definition of the term happened on March 31, 2018.

There’s another definition for Blue Moon. It can be the third of four full moons in a single season, with a season being between a solstice and equinox. The next seasonal Blue Moon will be August 22, 2021.

In recent years, people have been using the name Blue Moon for these two different sorts of moons: second of two full moons in a calendar month, or third of four full moons in a single season.

Someday, you might see an actual blue-colored moon. Meanwhile, the moon you’ll see on October 31, 2020, likely won’t look blue, and blue-colored moons in photos – like the ones on this page – are usually made using special blue camera filters or in a post-processing program such as PhotoShop.
