In the US (most of the US), daylight saving time begins this Sunday. So on March 14th, the second Sunday of March, the clock will jump from 1:59 AM to 3:00 AM.
How Daylight Saving Time started
The story goes that Daylight Saving Time was first proposed in the late 1800s. George Hudson presented the idea of a two-hour shift in time to the Royal Society of New Zealand (where he lived.) He was an entomologist who wanted to gather “the finest and most perfect collection of New Zealand insects.”
His problem was that it would get dark too early in the day so he had to stop his insect hunting. So he proposed advancing clocks two hours in summer and then shifted back in the winter, when he wasn’t bug-hunting.
Fast forward a few years and Ontario, Canada was the first city in the world to enact daylight saving time in 1908.
The big acceptance of daylight saving time came several years later. In the middle of World War I, the German Empire and some of its allies adopted it in an effort to conserve coal. Britain and some of its allies soon followed, with the United States adopting daylight saving time in 1918.
In today's society
One interesting fact about daylight saving time is that not all US states observe it. Arizona and Hawaii don’t observe daylight saving time. Most countries don’t follow it either.
Changing clocks is dangerous. It messes with people's internal schedules. As a result, fatal car crashes increase.
Fatal car accidents in the United States spike by 6% during the workweek following the “spring forward” to daylight saving time.
The entire week after daylight savings time begins is increasingly dangerous for drivers. I presume non-fatal, normal car accidents to be up during this week as well.
If you're having trouble remembering when to put clocks back versus when to set them forward, here's a phrase to help you remember:
spring forward, fall back
Meaning, the second Sunday in March daylight saving time begins and clocks go ahead one hour and daylight saving times ends the first Sunday in November and clocks go back one hour.
