August Full Moon name

Sturgeon Moon meaning

The August Full Moon is called the Sturgeon Moon, which is the traditional name for the Full Moon this month. Most known names for the Full Moon come from Native Americans, who based them on the features of a particular month. For many tribes living around the Great Lakes, August was traditionally the time to fish for sturgeon, hence the name for the August Full Moon.

A sturgeon is a large freshwater fish that has been living on the Earth since prehistoric times. Since then, they haven’t undergone any significant changes: some even call them living fossils. They can grow to over 2-3.5 meters long and weigh around 90 kilos. Female sturgeons can live up to 150 years; it takes them about 20 years to start reproducing, and they can only have offspring every four years.

There are about 26 sturgeon species worldwide, and all of them are endangered due to intense overfishing and water pollution. Let the name of the August Full Moon be a reminder to take care of nature.

Raksha Bandhan Moon

In Hindu culture, the August Full Moon marks the popular festival of Raksha Bandhan, a celebration of the bond between brothers and sisters. On this day, sisters tie rakhis (decorative threads) on their brothers' wrists, symbolizing love and protection. The term “Raksha Bandhan” means “knot of protection” in Sanskrit, highlighting the festival’s deeper meaning. Beyond siblings, rakhis are also exchanged among friends and neighbors.

The festival is celebrated on the Full Moon of Shravana, the fifth month of the Hindu lunar calendar, which falls between mid-July and late August.

August Full Moon alternative names
