At 2 a.m. Sunday, Nov. 5, most of the country will set their clocks back an hour and likely lose an hour of sleep.

The time shift, also referred to as “spring forward, fall back,” causes sleep disruption for Americans and requires some to manually correct clocks to the appropriate hour.

For those frustrated by the biannual shifts, there is hope as legislation has been introduced to prevent the end of daylight savings.

The U.S. Senate unanimously approved a bill called the Sunshine Protection Act in 2022. Introduced by Sen. Marco Rubio, R-Florida, the act would permanently extend daylight saving time for the entire year. However, the measure has not yet been signed into law by President Joe Biden as it hasn't yet been passed by the U.S. House of Representatives, where it was "held at the desk."
