North Korean leader Kim Jong Un celebrated his presumed 40th birthday on January 8, but Pyongyang's media maintained its decades-long tradition of silence on the occasion. While his birthdate has never been officially confirmed, the US government lists his birth year as 1984. Unlike his father and grandfather, whose birthdays are national holidays, Kim Jong Un's presumed birthday typically passes quietly. The closest acknowledgement was in January 2020 when North Korea confirmed Kim received birthday greetings from then-US President Donald Trump. State news agency KCNA showed Kim visiting a chicken farm with his daughter, Ju-ae, raising speculation about her potential succession. Kim's government faces heavy sanctions over nuclear weapons, ballistic missiles, and human rights abuses.
