When we change our watch
In most parts of the United States, daylight saving begins at 2:00 pm on the second Sunday in March and returns to standard time on the first Sunday in November. In the United States, each time zone changes at a different time. (daylight saving time)
In the European Union, summer begins and ends at 1:00 am Universal Time (Greenwich Mean Time). It begins on the last Sunday in March and ends on the last Sunday in October. In the EU, regions are always changing.

Spring in front, fall in the back
During DST, the clocks are one hour ahead, effectively removing daylight for one hour from morning to evening.

Spelling and grammar
The official spelling is daylight saving time, not daylight saving time.
Savings is used here as a verbal adjective (a participant). It changes time and tells us more about its nature; Namely, it is characterized by daylight saving activities. It’s time to save a day. For this reason, it would be more accurate to refer to DST as daylight-saving time. A similar example is a mind blowing book or a man eating a tiger. Used to save a ball game instead of a savings account.
Yet, one’s ownership is still beyond the reach of the average person. It is also available in general usage and dictionaries during daylight saving time.
Adding to the confusion is that the phrase saving time in daylight is incorrect, since daylight is not actually stored. Daylight transfer time would be better, and daylight transfer would be more accurate, but not politically desirable.
When in the morning?
In the United States, the clock strikes 2 p.m. Local time. In spring, the clocks run from 1:59 to 3:00 in the morning; In autumn, the clocks run from 1:59 to 1:00. In the spring, the clocks run from 12:59 to 2:00; In the fall, the clocks come back from 1:59 to 1:00
In the United States, daylight saving time begins at 2 p.m. However, many states prohibit the serving of alcohol between 2:00 and 00:00 in the fall, but the time is delayed by one hour. So, can bars serve alcohol for extra hours? Some states claim that bars actually stop serving wine at 1:59, so they have already stopped serving when the time comes back to standard time. Other states solve the problem by saying that alcohol can be given “two hours after midnight”. In practice, however, many institutions are open for an extra hour in the fall.
In the United States, 2:00 am was originally chosen as the time of change because it was practical and minimally interrupted. Most people were at home and this was the time when very few trains were running. It is too late to reduce the impact on bars and restaurants and this prevents the day from moving towards yesterday, which would be confusing. It’s early enough that the entire continental United States switches very quickly, and changes occur before most shift workers and primary church passengers are affected.
Some U.S. areas
For the United States and its territories, daylight saving time is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Commonwealth of Northern Mariana Islands, and Arizona. Due to the large size and location in the three states, Navajo participates in the national daylight conservation policy, even in Arizona.
A security reminder
Many fire departments encourage people to change smoke detector batteries when changing watches because they provide convenient reminders when saving daylight. “An effective smoke detector is twice as likely to survive a home fire,” said William McNab, of the Michigan Troy Fire Department. More than 90 percent of homes in the United States have smoke detectors, but one-third are estimated to have dead or missing batteries.
