Prvomayska St. Kacharevo (Serbia)

May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on 1 May, around halfway between the Northern Hemisphere's spring equinox and midsummer solstice. Festivities may also be held the night before, known as May Eve. Traditions include gathering green branches and wildflowers, 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. 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, the Gaelic festival Beltane, the Welsh festival Calan Mai, and May devotions to the Blessed Virgin Mary. It has also been associated with the ancient Roman festival Floralia.
