North Korea's Day of the Foundation of the Republic, a public holiday that often goes by the moniker Foundation Day, is coming up on Saturday, Sept. 9, and global investors will be watching closely for a bold move from the rogue nation.

Foundation Day is among the most important public holidays for the reclusive country, following Day of the Sun, the birthday of Kim Il-sung (leader of North Korea from 1948 until his death in 1994); Day of the Shining Star, which is the birthday of Kim Jong-il (leader from 1994 to 2011); and Party Foundation Day.

Foundation Day celebrates the proclamation of the Democratic People's Republic of Korea, DPRK for short, on Sept. 9, 1948. The DPRK was established after the Supreme People's Assembly promulgated a new communist, militaristic constitution on Sept. 3, 1948, a few years after the 1945 Liberation of Korea.
