The full moon in October 2023 is the Hunters Moon, and it will appear on Saturday, October 28, 2023. The Hunters Moon is fully illuminated and opposite the sun in its orbit around Earth. It is called the Hunters Moon because it is believed to originate as a call for hunters to venture out and hunt in preparation for the colder months ahead. Farmers had reaped the fields during the Harvest Moon, allowing hunters a better chance of spotting fattened deer and other game.
