Each year when DST ends, many wonder whether we gain or lose an hour of sleep; but the reality is we actually gain one extra hour when DST concludes - providing essential restful slumber!

Our clocks officially turn back by one hour at 2 a.m. on November 3, allowing us to switch our alarms back from two o'clock backwards to 1 am for another year of restful sleeping!

The choice of 2am as the time for DST change stems from its influence in the railroad industry - as this hour was seen as least disruptive to train travel during its implementation.

It's important to keep in mind that while we gain one hour of restful slumber in November, DST restarts in March causing us to "spring forward", meaning an hour less sleep overall.

Most states in the US participate in Daylight Saving Time, though there are notable exemptions such as Hawaii and parts of Arizona as well as various U.S. Territories such as American Samoa, Guam and Puerto Rico.

States' ability to opt-out of Daylight Saving Time is granted under the Uniform Time Act and they can thus break with this annual practice if desired.

Despite unanimous approval by the U.S. Senate in 2022, the Sunshine Protection Act did not become law, leaving the future of Daylight Saving Time uncertain due to other pressing priorities and a lack of consensus.

Looking ahead to 2024, Daylight Saving Time will commence on Sunday, March 10, with clocks springing forward, and conclude on Sunday, November 3, when clocks fall back again.
