Explained: What is US daylight saving time and why was it created? October 30, 2023 at 11:04PM

As countries prepare to end daylight saving time, the debate over whether to continue the practice is resurfacing in the US. Daylight saving time involves moving clocks forward by one hour during summer months to extend evening daylight. While many countries follow this practice, others do not. The idea originated in the late 19th century and gained traction during World War One. The US standardized daylight saving time in 1966, but states have the option to opt out. Some studies suggest adverse health effects from the time change.
