Kim Jong-un's birthday is observed in North Korea on January 8. This date is significant as it marks the birth of Kim Jong-un, who officially became the Supreme Leader of North Korea after the death of his father, Kim Jong-il, in December 2011. Kim Jong-un was groomed for leadership following the fall from grace of his older brother, Kim Jong-nam, in 2001. In 2009, he was named as his father's successor, and by 2010, he held the position of vice chairman of the Central Military Commission. Kim Jong-il had initiated a propaganda campaign to promote his youngest son, designating his birthday as an official holiday. Today, Kim Jong-un's birthday is celebrated as a major holiday in North Korea, reflecting the regime's continued emphasis on dynastic leadership.
