This year May Day is celebrated/ observed on Tuesday May 1st, 2018. May Day is observed on May 1. It is considered a spring holiday where celebrations include dancing and singing.
May Day is not a widely celebrated holiday and varies by region in the United States. Since 2006 with the passing of the "Illegal Immigration Control Act," May Day has become a time of protests mostly around immigration reform.
With the early European settlers to the Americas, May Day baskets were made filled with treats or flowers and left at someone's door step. The recipient receives the basket, trying to identify who the giver is who has run away. If the giver is caught, a kiss is exchanged.
