What is a Blue Moon? The modern day definition of a Blue Moon is when there are 2 Full Moons in one Month. A Full Moon occurs roughly every 29.5 days and on the rare occasions when the Full Moon falls at the very beginning of a month there is a good chance a Blue Moon will occur at the end of the month. According to this definition the next Blue Moon will occur on January 31, 2018.
