==May Day -Dark to Light==

May Day is a May 1 celebration with a long and varied history, dating back millennia. Throughout the years, there have been many different events and festivities worldwide, most with the express purpose of welcoming in a change of season (spring in the Northern Hemisphere).

The Celts of the British Isles believed May 1 to be the most important day of the year, when the festival of Beltane was held. This May Day festival was thought to divide the year in half, between the light and the dark.
