Leprechaun Day is celebrated on May 13, 2021. The day is about Irelands little folks, who also are celebrated on Saint Patrick's Day each year. According to Irish folklore, Leprechauns have a hidden pot of gold at the end of the rainbow and if a human is able to catch the Leprechaun, he has the magical power to grant three wishes in exchange for their freedom. So if you have always wanted a pot full of gold or a little green dressed guy, today is your day. Leprechaun Day can be used to search for rainbows and Leprechauns.
