During the Second World War (1939-1945), British Double Summer Time – two hours in advance of Greenwich Mean Time (GMT) – was temporarily introduced for the period when ordinary daylight saving would be in force. During the winter, clocks were kept one hour in advance of GMT to increase productivity.

“Sunday morning at 2 a.m. was when they would interrupt the least amount of train travel around the country,” Downing says. There were even fewer freight trains in the early 20th century than there are today, so it made the most sense — changing the clocks at 2 a.m. would not be disruptive.

Why are all clocks always 13?
Harry from the Beacon School solved this using an algebraic method. The sum of all the numbers is 78. If we call x the total on the small side, then 5x+x=78, so 6x=78 and x=13. So the sum on the small side is 13.
When did we alter the clocks by 2 hours?

What was the reason for changing time?
The true reason why DST was created was to create a way to save energy and to get more use out of our natural daylight. After the Energy Policy Act of 2005 was established, every state or territory in the U.S. had the choice to opt-in or opt-out of DST.

It no longer serves its intended purpose of saving electricity, and DST negatively impacts our health, is overly complicated, costs us money, and puts our most vulnerable populations at risk. Americans deserve better. We should propose sweeping legislation to end DST in our country.
