My 200th post!May Day is May 1, and refers to any of several holidays celebrated on this day. May 1 was a traditional summer holiday in many pre-Christian European pagan cultures, and many elements of these holidays are still celebrated on May 1 today, such as the Maypole. While February 1 was the first day of Spring, May 1 was the first day of summer: hence, the summer solstice on June 25 (now the 22nd) was "midsummer."
In the Roman Catholic tradition, May is observed as Mary's month, and May Day is usually a celebration of the Blessed Virgin Mary. In this connection, Mary's head (in works of art, school skits, etc.) will often be adorned with flowers. Another May Day tradition (fading in popularity since the late 20th century) is the giving of May baskets, small baskets of candy and/or flowers, usually left anonymously on neighbors' doorsteps.
