when is daylight savings

Daylight Savings Time (DST) is an adjustment of the clock that is used to make better use of daylight and save energy. It is observed in many countries around the world, including the United States and Canada. DST typically starts on the second Sunday in March and ends on the first Sunday in November. During DST, clocks are set ahead one hour from the standard time. This means that when it is 8:00 AM standard time, it is 9:00 AM during DST.

The concept of daylight savings was first proposed in 1895 by George Vernon Hudson, an entomologist from New Zealand. It was not until World War I that the idea was widely adopted, as countries began to use it to save energy during wartime. In the U.S., DST was officially adopted in 1966 by the Uniform Time Act. Since then, DST has been observed in most states, with a few exceptions. Arizona, Hawaii, Puerto Rico, the Virgin Islands, and American Samoa do not observe DST.

The purpose of DST is to make better use of the available daylight during the summer months. By setting the clocks ahead one hour, people have an extra hour of daylight in the evening. This reduces the need for artificial lighting, which can help to conserve energy. In addition, many studies have shown that DST can have a positive effect on the economy, as people have more time to shop and spend money.
