Daylight saving time (DST) is the practice of advancing clocks during warmer months so that evenings have more daylight and mornings have less. In the United States, DST begins on the second Sunday of March and ends on the first Sunday of November. In 2025, DST will begin on March 9th and end on November 2nd.
DST has a number of benefits, including reducing energy consumption, decreasing crime rates, and improving public health. Studies have shown that DST can lead to a decrease in traffic accidents, as well as a reduction in the number of pedestrian fatalities. Additionally, DST can help to improve sleep quality and reduce the risk of obesity.
