Koreans celebrate two birthdays, which may seem odd to outsiders, but it is an important part of Korean culture that has deep roots in history and tradition. One of the main reasons why Koreans have two birthdays is because they follow both the lunar and solar calendars. The celebration of two different birthdays reflects the importance of family connections and individuality in Korean culture. Respect for elders, family connections, and individuality are all fundamental parts of Korean culture that are reflected in the way birthdays are celebrated.
