Trooping The Colour

The Queen, who was born on April 21, 1926, celebrated her birthday this year privately with members of the royal family. Since the occasion also fell on Easter Sunday, the royal attended church services with family.

While the Queen typically celebrates her actual birthday privately, it’s also customary to celebrate a sovereign’s birthday publicly on a day during the summer, when the weather is nicer. The royal family gathered together last weekend for Trooping the Colour, the monarch’s annual birthday parade.
