Daylight saving time begins tonight in 2025 when the clocks will move forward by an hour. Let’s take a closer look at when this time change occurs and how daylight saving time functions.
What time exactly will the time change take place for daylight saving in 2025?
The time change will occur at 2 a.m. on Sunday, March 9, transitioning to 3 a.m.
How does the time change work during the spring?
During the spring, clocks are moved forward by one hour, resulting in the sun setting an hour later in the evening and rising an hour later in the morning. Digital clocks such as those on cellphones will adjust automatically. Analog clocks and those that do not automatically adjust will need to be manually reset. This adjustment results in losing an hour of sleep. Studies have shown that this change is linked to various health issues, including an increase in strokes, heart attacks, and traffic accidents in the days following the time change.
When does daylight saving time end in the fall?
This year, daylight saving time ends on Sunday, November 2, when clocks will “fall back” by one hour. Following this change, the sun will set an hour earlier in the evening and rise an hour earlier in the morning.
Which countries implement daylight saving time outside the U.S.?
Outside the U.S., the majority of countries that observe daylight saving time are located in Europe. Countries such as France, Italy, Spain, Germany, the United Kingdom, and Switzerland commonly practice daylight saving time. Additionally, parts of Canada and Australia observe this time adjustment. Egypt is the sole African country that observes daylight saving time.
Which U.S. states do not observe daylight saving time?
Hawaii and most of Arizona do not participate in daylight saving time. Similarly, the U.S. territories of American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and U.S. Virgin Islands do not practice daylight saving time.
Who is credited with inventing daylight saving time?
While some attribute the origins of daylight saving time to Benjamin Franklin in 1784, others point to New Zealand entomologist George Hudson, who proposed a two-hour clock rollback in 1895. Additionally, British builder William Willet advocated for moving clocks forward in the spring in order to promote early rising. The current practice of commencing daylight saving time on the second Sunday in March and ending it on the first Sunday in November was established under former President George W. Bush.
