Birthdays are always cause for celebration but doubly so if you’re Queen Elizabeth II.

The monarch celebrates her actual 91st birthday on April 21. But every year, she also celebrates a second “official” birthday on a Saturday in June. That’s marked with a military parade known as Trooping the Colour – and this year it falls on June 17.

The reason behind the double celebration is Britain’s temperamental weather. It’s a tradition that dates back to 1748 when King George II, who was born in November, thought it was too cold to host an annual birthday parade at that time of year.
