24th century BC

In modern Korean national mythology, the character Dangun, whose mother was originally a bear, founded the state Gojoseon in 2333 BC and ruled it for about 2000 years.

From 1948 until December 1961, the Republic of Korea officially[2] reckoned years by adding 2333 to the Common Era year.

The year 2333 BC and the related myth are sometimes presented matter-of-factly as history rather than mythology in Korea.

In Jewish and Christian history, sometime near the middle of the 24th century BC,[4] the (known) world was flooded, covering the tops of mountains, and destroying the human and land animal populations.

Only the family of a man named Noah, and one breeding pair of each animal type survived the flood by floating in/on a large wooden boat for several months.
