May Day is related to the Celtic festival of Beltane and the Germanic festival of Walpurgis Night. May Day falls half a year from November 1 – another cross-quarter day which is also associated with various northern Europeanpaganisms and the year in the Northern Hemisphere – and it has traditionally been an occasion for popular and often raucous celebrations.
As Europe became Christianized, the pagan holidays lost their religious character and either changed into popular secular celebrations, as with May Day, or were merged with or replaced by new Christian holidays as with Christmas,Easter, and All Saint's Day. In the 20th and continuing into the 21st century, many neopagans began reconstructing the old traditions and celebrating May Day as a pagan religious festival again. Note that the source noted does not support any of the changes claimed by the previous statement. The only significant Christianization of May day is essentially localized to Germany where it is one of many historic days that were used to celebrate St. Walburga (the saint credited with bringing Christianity to Germany).
