The "Full Flower Moon" rises this Saturday

A common (if disputed) definition of a blue moon is that it's the second full moon in a given month-which does not apply here. In the first season of the four seasons of the year, if the 4 full moon comes, then the third full moon is given the name of the Blue Moon.

"When that happens, the third full moon of that seasonal lunar quartet is designated as a Blue Moon - although no one is quite sure why the third, and not the fourth, is the one that gets the Blue Moon moniker". The explanation gets a little convoluted, but the easy part is that May's full moon is often called the "flower moon" because of all the spring blooms, reports CNN. However, what's curious about this one is that it's going to be the last until August 22, 2021, making it the final blue moon of the decade. In most seasons, there are just three full moons.

Hang on, isn't a Blue Moon defined as the 2nd full moon that occurs during a calendar month?

Talking about any Blue Moon involves a lot of technical Blue Moon information because Blue Moons are calculated two different ways - seasonally and monthly.

According to EarthSky astronomers, the last seasonal blue moon was on May 21, 2016. Pink Moon 2019: Gorgeous Full Moon Graces Skies Across the World on Good Friday, Check Pics And Videos.
