May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on May 1, around halfway between the Northern Hemisphere's spring equinox and midsummer solstice.[1][2] Festivities may also be held the night before, known as May Eve. Traditions include gathering green branches and wildflowers ("bringing in the May"

,[3] which are used to decorate buildings and made into wreaths; crowning a May Queen, sometimes with a male companion decked in greenery; setting up a Maypole, May Tree, or May Bush, around which people dance and sing; as well as parades and processions involving these.[4] Bonfires are also a major part of the festival in some regions. Regional varieties and related traditions include Walpurgis Night in central and northern Europe,[1] the Gaelic festival Beltane,[5] the Welsh festival Calan Mai,[5] and May devotions to the Blessed Virgin Mary. It has also been associated with the ancient Roman festival Floralia.[6]
International Workers' Day observed on 1 May is also called "May Day", but the two have different histories.
Early European settlers of the Americas brought their May Day traditions with them, and May Day is still celebrated in many parts of the United States, with customs that vary from region to region. In some parts of the United States, May baskets are made. These are small baskets usually filled with flowers or treats and left at someone's doorstep. The giver rings the bell and runs away.[63][64]

May Day celebrations were common at women's colleges and academic institutions in the late nineteenth and early twentieth century, a tradition that continues at Bryn Mawr College[65] and Brenau University[66] to this day.
