"Hallmark holiday" is a term used predominantly in the United States to describe a holiday that is perceived to exist primarily for commercial purposes, rather than to commemorate a traditionally or historically significant event. The name comes from Hallmark Cards, a privately owned American company, that benefits from such manufactured events through sales of greeting cards and other items. Holidays that have been referred to as "Hallmark holidays" include Grandparents Day, Sweetest Day, Boss's Day, and Secretary's Day. Some people also consider St. Valentine's Day, Mother's Day and Father's Day to be such days.
