Queen Elizabeth II: The Longest Reigning British Monarch In Numbers

The Longest Reigning Monarch In Numbers
|

Queen Elizabeth II has surpassed her great great grandmother Queen Victoria to become the longest serving British monarch in history.

The 89-year-old has worn the crown for 62 years and 217 days and in her time she has seen 237 streets named after her. That's a lot of tarmac.

Her Majesty has also overseen a total of 12 Prime Ministers and ruled a doggie dynasty of more than 30 corgis.

Here's the Queen in even more numbers:

As the second-longest serving monarch in the world, the Queen has made many landmark decisions.

She was the first British monarch to have sent an email, to have a message put on the moon, have conducted a royal ''walkabout'' and to have held a public concert in her back garden.

The length of time on the throne can be calculated in different ways, but the Palace considers the total number of days plus hours and minutes to be the most accurate.

The Queen passes Victoria's record at around 5.30pm on Wednesday when she will have reigned for 23,226 days 16 hours and approximately 30 minutes – but the exact moment she became Queen is hard to calculate as George VI died in his sleep in the early hours of the morning, possibly at around 1am.
