Once again, most Americans will set their clocks forward by one hour this weekend, losing perhaps a bit of sleep but gaining more glorious sunlight in the evenings as the days warm into summer.
Where did this all come from, though?
How we came to move the clock forward in the spring, and then push it back in the fall, is a tale that spans over more than a century — one that’s driven by two world wars, mass confusion at times and a human desire to bask in the sun for a long as possible.
There’s been plenty of debate over the practice, but about 70 countries — about 40% of those across the globe — currently use what Americans call daylight saving time.
While springing the clocks forward “kind of jolts our system,” the extra daylight gets people outdoors, exercising and having fun, says Anne Buckle, web editor at timeanddate.com, which features information on time, time zones and astronomy.
Here are some things to know so you’ll be conversant about the practice of humans changing time:
How did this all get started?
In the 1890s, George Vernon Hudson, an astronomer and entomologist in New Zealand, proposed a time shift in the spring and fall to increase the daylight. And in the early 1900s, British homebuilder William Willett, troubled that people weren’t up enjoying the morning sunlight, made a similar push. But neither proposal gained enough traction to be implemented.
Germany began using daylight saving time during World War I with the thought that it would save energy. Other countries, including the United States, soon followed suit. During World War II, the U.S. once again instituted what was dubbed “war time” nationwide, this time year-round.
In the United States today, every state except Hawaii and Arizona observes daylight saving time. Around the world, Europe, much of Canada and part of Australia also implement it, while Russia and Asia don’t currently.
