Get ready to ‘spring ahead’ as daylight saving time starts Sunday

Pennsylvanians will lose an hour of sleep Sunday as clocks “spring forward” for daylight saving time.

Clocks will change at 2 a.m, skipping an hour ahead, making sunset later in spring and summer and allowing for more light during the day.

Daylight saving time started in World War I as an energy-saving measure and was hugely unpopular. In 1942, President Franklin D. Roosevelt instituted a yearlong daylight saving time to help conserve energy again.

Is it worth changing the clocks?

There’s no definitive answer, but some studies suggest daylight saving time does help businesses.

Longer daylight hours can allow people to spend more time shopping or doing activities after work. The extra hour helps all kinds of industries and businesses, like gas, shopping malls, restaurants and outdoor activities, the CBC reports.

Could we just stay on daylight saving time all year?

No, due to the Uniform Time Act of 1966 that standardized time zones for the U.S.

Any state wanting to stick to daylight saving full time would have to get congressional approval.

In April, the Pennsylvania House of Representatives passed a bill to make daylight saving time permanent. The bill has not passed the state senate.

In a memorandum, state Rep. Ryan Mackenzie, R-Lehigh County, said he would reintroduce legislation, claiming changing the clocks added “unnecessary stress.”

Only two states don’t follow daylight saving time, Arizona and Hawaii, which stay on permanent standard time instead.
