According to Irish folklore, a leprechaun is a type of fairy that is usually represented as an old man, clad in a red or green coat, and who enjoys being mischief.
Leprechauns spend their time making shoes. Another thing to know about them is that they store their coins in a hidden pot of gold at the end of the rainbow.
There is a rumor going around saying that if you catch a leprechaun, he has to give you his pot of gold. Unfortunately, leprechauns are very tricky to catch.
You can celebrate this day by adding to a saving account or by simply watching leprechaun-related cartoons.
