Black Day (April 14) is a South Korean informal tradition for single people to get together and eat jajangmyeon (white Korean noodles with black bean sauce), sometimes a white sauce is mixed for those who did not celebrate White Day.
The idea is that those who did not give or receive gifts on Valentine's Day (February 14) or White Day (March 14) can get together and eat jajangmyeon (white Korean noodles with black bean sauce) hence the name, to celebrate being single.
