Queen Elizabeth II will on Wednesday pass the landmark for longest-reigning monarch set by Queen Victoria. Here are some figures about her reign, which has lasted more than 63 years:
- 33,446,430 minutes or 23,226 days, 16 hours and 30 minutes is the amount of time the queen will have spent on the throne when she breaks the record on September 9 at roughly 5:30 pm (1630 GMT).
- 12 prime ministers have been in power during her reign. The first was Winston Churchill, who mentored her when she first took the throne aged 25 in 1952, and the most recent is David Cameron.
- 10 hours spent delivering her 62 Queen's Speeches, delivered at the state opening of parliament and written for her by the government of the day to outline its legislative plans.
- 56 Christmas messages delivered to the nation. It is a ritual for many British families to sit and watch the queen's festive message on television after eating their Christmas lunch.
- 97 state visits, the first to Norway in 1955 and the most recent to Germany in June. Despite her extensive travels, the queen does not possess a passport.
- 50,000 people on average are invited every year to garden parties, dinners and other events hosted by the queen.
- 67 years of marriage to Prince Philip whom she has called my strength and stay. The couple were married on November 20, 1947.
- The world's longest-serving living monarch is Thailand's King Bhumibol Adulyadej, who has reigned for six years longer than the queen.
