The birthday of Queen Silvia is observed in Sweden every December 23, marking an official flag day in the country. Queen Silvia, born on December 23, 1949, in Heidelberg, Germany, became the queen consort of Sweden after marrying then-Crown Prince Carl Gustaf in 1976. The couple met during the 1972 Summer Olympics, where Silvia was an educational host. Queen Silvia is well-regarded for her involvement in various charitable organizations, particularly those focused on helping disabled children and child victims of sexual abuse. She established a fund that supports at-risk children and operates in 17 countries. Celebrations typically include public recognition of her contributions and the display of flags in her honor.
