Just across the river from the square is the Juche Tower, named for the ‘Juche’ idealogy introduced by Kim il-Sung. Juche is the official state ideology of North Korea and is usually translated as “self-reliance.”
They are really serious about their Juche. North Korea actually follows something that they call the “Juche Calendar.” In this calendar, ‘year 1’ is in 1912, the year when Kim il-Sung was born. This means that the current year in North Korea is “Juche 106,” not 2017.
