The wolf moon is the first full moon in the month of January. The time of the Wolf Moon happens in the depths of winter when wolves howled hungrily outside the villages of the native people. It's also sometimes referred to as the Old Moon.
The farmer's almanac included nicknames for the full moon depending on what month they occured. Most of these nicknames were based on the names North American aboriginal people used. Although many tribes gave nicknames to the full moon, the most well known come from the Algonquin tribes who lived in the area of New England and westward to Lake Superior.
