Pepero Day is an observance in South Korea similar to Valentine's Day. It is named after the Korean snack Pepero and held on November 11, since the date "11/11" resembles four sticks of Pepero.^[1][2] The holiday is observed mostly by young people and couples, who exchange Pepero sticks, other candies, and romantic gifts. Lotte denies starting the holiday and instead states that they noticed a bump in Pepero sales around November 11th and after continued popularity they decided to then encourage the holiday with special gift boxes and other promotions. Some consider it to be a contrived holiday and some teachers have encouraged children to exchange healthy snacks to help combat obesity. An alternative "Garaetteok Day" (sticks of white tteok) has been proposed.^[3]

According to one story, Pepero Day was started in 1994 by students at a girls' middle school in Busan, where they exchanged Pepero sticks as gifts to wish one another to grow "as tall and slender as a Pepero"
