The birthday of Princess Marie of Denmark is celebrated on February 6. This occasion is observed in Denmark as a flag-flying day, although it is not a public holiday. Princess Marie, born Marie Cavallier in Paris in 1976, is the second wife of Prince Joachim, the younger brother of King Frederik X. After her parents' divorce, she moved to Switzerland and later pursued studies in international business and economics in the United States and Switzerland. Marie became engaged to Prince Joachim in 2007 and they married in 2008, having two children together while also being stepmother to Joachim's sons from his first marriage. Notably, her birthday falls right after that of Queen consort Mary, further linking her to the Danish Royal Family.
