Look At How Britain’s Longest Serving Monarch, Queen Elizabeth II Will Celebrate

               Queen Elizabeth II is planning to keep things low-key on Wednesday when she will overtake Queen Victoria as Britain’s longest-serving monarch, despite public interest in the historic date.
The queen will ride on a steam train in Scotland to inaugurate a new railway line and will host a dinner at Balmoral Castle with her grandson Prince William and his wife Kate in attendance.
According to calculations by royal officials, at around 1630 GMT Elizabeth will beat her great-great grandmother Victoria’s time on the throne: a total of 63 years, seven months and two days which she served between 1837 and 1901.

The exact hour has been difficult to determine because the exact start of her reign — the moment when her father George VI passed away  is difficult to work out as the king died at night in his sleep.
The 89-year-old Elizabeth, also the world’s oldest monarch, had originally not planned anything special for the day itself but reportedly agreed to a public appearance due to public pressure.

“You need to remember for the queen this is a date whose calculation rests on the death of her father and great-great grandmother. That naturally colours the way she sees it,” a royal source said.
“While she acknowledges it as an historic moment, it’s also for her not a moment she would personally celebrate, which is why she has been keen to convey business as usual, and no fuss,” the source said.
