The moon goes through a series of phases as it travels around the earth, changing from a new moon to full moon every 29.5 days. There have been many names given to the time when the moon is full. The Farmer’s Almanac lists the following names:
The term, “Blue Moon,” refers to two full moons occurring in a single month, such as those in 2018 during January and March. The next Blue Moon will appear on October 31, 2020. The Blood Moon is a name given to the moon during a full lunar eclipse, when the Earth blocks direct sunlight from reaching the moon. The only light reaching the moon is that which is refracted from the earth. This diminished light imparts a deep reddish color
to the moon. The most recent Blood Moon occured on January 21, 2019. It is very rare to have a month in which there a no full moons. This only occurs in February, our shortest month. It only happened four times in the last century; the next time this will occur will be February, 2066.
A full moon occurring on a Monday is considered to be good luck, but a full moon on Friday the 13 th is supposed to bring bad luck. A study by a British medical journal stated that dog bites requiring a hospital visit were twice as common during full moons versus any other time.
The moon can appear white, blue, red, or orange, depending on the amount of dust in the atmosphere and the angle of the moon in relation to the sun. In the fall, the moon tends to be orange in color.
