While Brits enjoy an extra hour in bed this weekend, royal staff have spent hours turning back the 1,500 timepieces inside Her Majesty’s official residences. 

The clock change, which takes place on the last Sunday in October, means that at 2am yesterday, the time in the UK went back down to 1am, as Greenwich Mean Time took over British Summer Time.

The Royal Family reminded Brits of the clock changing by sharing a glimpse into the timepieces at Windsor Castle, Berkshire. Her Majesty is currently in recovery after a stay in hospital.

The weekend was spent by a team of horological conservationists, who worked tirelessly to fix the 400 timepieces that were on the estate. There are 250 of them inside the castle.

‘Did you know there are over 1,000 clocks within Her Majesty’s official residences?

“Each timepiece will be conserved by a specialist horologist, and each will have an hour set back this Sunday. 

The Horological Conservator of Windsor Castle shared footage of the timepieces. He explained that it takes much longer to wind the clocks backwards in winter than it does to turn them forward in summer.

“We have 400 clocks on our estate, 250 of which are in the castle, and the rest scattered around the estate. He said that he winds them up once a week so he knows every clock well. 

“Just like a car needs an MOT every now, a clock will require a service every couple years. We have the clock changed twice a year. 

“In summer the clocks go forward, while in winter they go backwards. When we set the clocks backwards in winter it’s a different process for every clock, in summer it’s much easier because every clock just goes forward one hour and each time it takes me about a weekend to set all the clocks to the right time.’  

The royal estates features musical, astronomical and miniature clocks including 600 at the Queen’s official London residence Buckingham Palace and 50 at the Palace of Holyroodhouse in Scotland.

Farmers and workers could get another hour of daylight by moving their clocks forward each year in the heat, in a tradition enacted with the 1916 Summer Time Act.

Originally, this was done to aid the war effort since there was more daylight in the evenings.  

Her Majesty is currently resting at Windsor Castle on advice of royal doctors after undergoing medical tests and spent a night at London ´s King Edward VII´s Hospital, her first such stay in in eight years. 

Although she has cancelled all her working visits for the next week, the Queen has continued to work from her hospital visit and will continue with desk-based duties.

Her Majesty, who used a walking stick for the first time during a royal visit this month (seen at Westminster Abbey), is currently recovering at Windsor Castle but is keen to make a speedy recovery in time for the holiday

Her Majesty, who was seen at Westminster Abbey with a walking stick during a royal visit this past month, is currently in Windsor Castle recovering. She is hoping to make a quick recovery so she can be back on time for the holiday.

During her time off, she will not be able to attend the U.N. Climate Summit in Glasgow, Scotland on Sunday. However, she has recorded a message for attendees. 

She will also miss the Nov. 13 Festival of Remembrance at London’s Royal Albert Hall, which is an event that honours the British and Commonwealth men, women, and children who have fought wars and disasters to defend and defend the nation.

However, the palace said it is the queen´s ‘firm intention’ to be present for a Remembrance Sunday ceremony in central London on Nov. 14.

Since her last public appearance two weeks ago, The Queen has only performed virtual engagements. Yesterday, she presented the Queen’s Gold Medal in Poetry to David Constantine, an English poet, who was at Buckingham Palace.
