In the Almanac(page 127), why is the August 31st full moon named the "red moon" instead of the blue moon?
I believe this name is one of the names given to a full moon in August. Each full moon has a special name given to it depending on what month it's present. For example, the September moon is also known as the Harvest Moon. Furthermore, a blue moon is actually the third out of four moons in a season, instead of the second full moon in a calendar month. The definition of "Blue Moon" was made incorrect back in the 40s by a newspaper article and wasn't corrected until 1999 so it is understandable why some still believe it to be the second full moon in a calendar month. Hope this helps.
July 3 is the first full moon of the season. Followed by August 2 then August 31. The next one is September 30, which is after the autumnal equinox. So there's only three full moons in the summer season therefore no blue moon.
