Pocky & Pretz Day (ポッキー＆プリッツの日, Pokkii & Purittsu no hi) is a Japanese marketing event that occurs on 11 November each year. The event uses the Ezaki Glico products Pocky and Pretz, which are both long and thin biscuits, to represent the repeated number 1 in the numerical date (i.e. the 11th day of the 11th month).^[1] Ezaki Glico has deployed an advertising campaign surrounding the date each year since 1999.^[2] Pocky & Pretz Day has been certified as a memorial day by the Japan Anniversary Association (日本記念日協会, Nihon Kinenbi Kyoukai).^[2]
