As their shapes resemble the number 1, both Pepero Day and Bar Rice Cake day are held every year on November 11.

Pepero Day is one of Korea’s unique anniversary in which people give Pepero, a biscuit stick covered or filled with chocolate, to one another. A tradition that goes back since 1995, it is believed that if students eat Pepero sticks 11 days before Korea’s college scholastic ability test, they will get good grades. Another theory of the origin of this day is that in Busan, female students gave out Pepero for fun to cheer each other up and to become thin like the chocolate sticks.

 
Bar Rice Cake Day began in 1996. On this day, many bar rice cake related events are held. For example, Korea’s rice museum’s website has fill in the blank quizzes regarding bar rice cakes and there are also performances with the cakes.

In 2003, AhnLab Inc., one of Korea’s information security business enterprise, held a bar rice cake event instead of using Pepero.
