Everything You Need to Know About Daylight Saving Time

There’s good news for everyone who likes their sleep: Sunday, November 7th is Daylight Saving. AKA, people in the Northern Hemisphere get to enjoy an extra hour of sleep. 

Daylight Saving Time (DST) ends at 2 a.m., and the clocks go back an hour. 

When you think it’s 8 a.m. and time to get up, it’ll be 7 a.m., and you can go back to sleep for another hour. But why do we make these strange adjustments to our schedule, and what dates do we need to remember to make sure we’ve got the time right? 

When does Daylight Saving Time Start and End?

Until 2007, Daylight Saving Time began on the last Sunday of April and ended on the last Sunday of October in the U.S. and Canada. This was in line with Europe. Now, the clocks “fall” back to Standard Time at 2 a.m. on the second Sunday of March and then “spring” forward again on the first Sunday of November.

Hawaii and Arizona don’t observe Daylight Saving Time. They opted only to follow Standard Time in the 1960s, and Tennessee is one of several states awaiting Congressional approval to adopt DST all year round. 

Why Does Daylight Saving Time Exist?

The popular myth is that Daylight Saving Time started to help the farmers have more time to tend to their animals and crops when it’s light outside. But, there are several different origin stories. 

The first story dates back to 1784, when a satirical letter from Benjamin Franklin suggested that waking up earlier in the summer would help reduce candle usage. Then New Zealand entomologist and astronomer George Hudson proposed changing the clocks by two hours every spring to have more daylight hours to collect and examine insects. In the UK, William Willett proposed the idea in 1907 as a way to save energy.

In 1916, the German Empire and Austria-Hungary were the first places to implement DST nationwide.

President Lyndon B. Johnson signed the Uniform Time Act in 1966 to adopt DST as a national standard. The idea was to conserve energy as you don’t need the lights on for so long.

What Do I Need to Know About Daylight Saving Time?

Aside from getting an extra hour’s sleep when DST ends, there isn’t anything else you need to know or do. Your cell phone and other digital devices will almost certainly adjust automatically, so you don’t need to change your alarms. 

Often, the only clocks you need to adjust manually include your cooker and your car. Or maybe you’ll just leave them until the spring when Daylight Saving Time starts, and the clocks go forward again!
