Prepare to lose an hour, Oxford; daylight savings time will begin at 2 a.m. Sunday, March 13, when you should reset your clocks to 3 a.m. It’s a good idea to set manual clocks forward before heading to bed Saturday night to ensure events scheduled for the morning go according to plan.

The daylight savings period begins on the second Sunday of March every year. Clocks return to standard time on the first Sunday of November because of a federal policy enacted in 1966. 

According to the National Conference of State Legislatures (NCSL), while the legislation enforces daylight savings time (DST) across America, several states and territories were excluded including Hawaii, the majority of Arizona, Puerto Rico, and the U.S. Virgin Islands.

There are several reasons the legislation was enacted. According to the U.S. Department of Transportation, DST saves energy because the sun goes down later and comes up earlier, thus, reducing the need for household lighting. The Transportation Department also said that DST saves lives and prevents traffic accidents because more people travel and complete their tasks during daylight. This factor also helps to reduce crime as an abundance of crimes occurs in the dark.

Despite the intention behind the legislation, according to the NCSL, almost every state has considered legislation that would make the observance of just standard time or just daylight savings time permanent.

Complaints surrounding the time change include having to change manual clocks, venture home in the dark, and issues re-adjusting an internal sense of time. Since 2015, at least 350 bills and resolutions have been introduced surrounding DST. However, no significant bills were passed until 2018 when Florida decided to permanently observe DST pending an amendment to the federal law.

In the past four years, 18 states including Ohio have also enacted legislation or resolutions to switch to year-round daylight savings time but congress has not yet allowed for this change to take place.
