To be fair a ‘Blue Moon‘ can mean one of three things:

1. Second full moon within the same calendar month.

2. Third full moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.

3. When the moon, due to atmospherical conditions, appears blue.

All three are RARE events. An astronomical season is but three months. So to get 4 full moons does not happen that often. DITTO for two full moons in the same month and ‘red’, ‘orange’, ‘silver’ and ‘gray’ moons are much more common that blue-tinted moons.

So the phrase, ‘Blue Moon’, as I talked about in this post, is also used to mean something that happens rarely.

The last two full moons in a month happened in September 2012. Nearly 3 years ago.

Friday’s July 31, 2015 Blue Moon is the last, for us in EASTERN U.S. till beyond 2020. Yes, that is it for over 5 years. Time zones to the WEST of us will have them in May 2016, May 2018 and October 2020. But not in Eastern U.S. All has to do with the timing of the 2nd full moon.

Third full moon in an astronomical season will happen May 2016, May 2019, August 2021 and August 2024.

Plus, July 31, 2015 is “National Orgasm Day“!

It has to the first time NOD has happened in a Blue Moon. Wow.
