White Day - Wikipedia, the free encyclopedia

White Day - Wikipedia, the free encyclopedia: "There are many theories about the origins of White Day, but according to one, the holiday began in 1965, when a marshmallow maker started marketing to men that they should pay back the women who gave them chocolate and other gifts with marshmallows. Originally it was called Marshmallow Day, and later it was changed to White Day.

Soon, the chocolate companies started realizing that they could capitalize as well on this day, and began marketing white chocolate."
