South Korea

In South Korea, Valentine's Day is a popular celebration for young couples, and variations of the event are observed monthly from February through April. The gift-giving season begins on February 14th, when women woo their men with chocolates, candy, and flowers. On March 14th, known as White Day, men not only shower their sweethearts with chocolates and flowers but also boost the ante with a gift.

There is a third holiday, Black Day, for individuals who don't have anything to celebrate on Valentine's Day or White Day. Singles traditionally grieve their alone existence on April 14th by eating dark bowls of jajangmyeon, or black bean paste noodles.
