The next upcoming May Day is on Saturday May 1st, 2021.
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.
