Queen's homes will all undergo similar modifications this weekend

The Queen's homes will all undergo similar modifications this weekend as the painstaking task that is changing every single one of the royal clocks is exposed. Ahead of the clocks going forward an hour, it will be all hands on deck for the bi-annual mission.

• The Queen's homes are said to have over 1,500 clocks—all of which need to be changed by hand.
• Each year the job requires a whole team of experts to spend 40 hours on a weekend.
• In other royal news, Prince Charles' cake-cutting—hilarious method is the exact same as the Queen's

In Buckingham Palace, Windsor Castle, Balmoral Castle, and every royal residence in-between—time is kept by very precious and historic clocks. Nope, it's not all digital in the halls of these residences, meaning that all of these chronometers need to be changed by hand.

Not just any old hands say the Royal Collection Trust, whose team of experts will spend over 40 hours this weekend as the clocks go forward and British Summer Time officially begins.

The biannual event sees the experts, known as 'Horological Conservators,' work together to get the job done. According to the Royal Collection Trust, these individuals will, "work through the weekend to adjust the clocks, including 450 timepieces at Windsor Castle, 600 at Buckingham Palace and 50 at the Palace of Holyroodhouse."

As one might expect, the Royal Collection is home to some of the most valuable clocks in the world. Clocks that tell a lot more than the time.

The RCT explains, "they reflect mechanical innovation over the centuries and the tastes of successive monarchs," and include, "musical clocks, astronomical clocks, miniature clocks, and turret clocks."

Although it's unclear if Her Majesty has a keen interest in these historical timepieces, she's certainly proven herself to be knowledgeable in other niche topics. This was proven when the Queen's nerdy trick was unveiled to unsuspecting lunch guests.
