The Beaver Moon is the full moon that appears in November. It is called the Beaver Moon because it corresponds to the time of year when beavers start sheltering in their lodges, according to the Old Farmer's Almanac. This is also historically the time of year when beavers would be trapped as part of the fur trade. The November full moon is also known by other names such as the Digging Moon, the Frost Moon, the Freezing Moon, the Deer Rutting Moon, and the Whitefish Moon, highlighting the onset of colder weather and the actions of animals preparing for winter
