National Day (Zhenia)

National Day (Zhenian: 국가창건일) in Zhenia, also referred to as Imperial Day (Zhenian: 제국절) or Unification of the Five Jins Day (Zhenian: 오진통일절), is a national holiday in Zhenia commemorating the establishment of the Empire of Zhenia as well as the unification of Zhenia and the formation of the modern Zhenian state, on June 4, 1438 AC. Emperor Seongjo's imperial as well as the declaration of the Empire of Zhenia took place, while the full unification of Zhenia under the new empire was also announced the same day.

In addition to major national and civil events commemorating the establishment of the modern Zhenian state, celebrations for National Day include military parades in major cities, smaller civil parades all across the nation, concerts, late night shows, festivals and firework displays across the nation. Although there have been movements to instead designate Republic Day as its national day, National Day remains as the of Zhenia to this day.
