May Day
May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on May 1, around halfway between the spring equinox and summer solstice. Festivities may also be held the night before, known as May Eve. Traditions often include gathering wildflowers and green branches, weaving floral garlands, crowning a May Queen (sometimes with a male companion), and setting up a Maypole, May Tree or May Bush, around which people dance.
