Daylight savings time is a common practice in many countries around the world. It is a way to extend daylight hours during the summer months, which means that clocks are advanced one hour in the spring and turned back one hour in the autumn. There are many synonyms for daylight savings time, including daylight time, summer time, and DST. These terms all refer to the same practice of adjusting clocks to take advantage of longer daylight hours. While some people disagree with the practice of daylight savings time, it remains an important tradition in many parts of the world and helps to ensure more daylight hours for outdoor activities and efficiency.
