Hi Laura, According to NOA's website, each number "1" is regarded as one side of square, therefore Nov. 11th (11th day of 11th month) is the Origami Day in Japan. Nov. 11th is also the World Peace Memorial Day (when the World War I Treaty of 1918 was signed), which aligns with the peaceful practice of origami.
