Is it Daylight “Saving” or “Savings” Time?
The official term is Daylight Saving Time (DST), with “saving” as a verb. The idea behind the name is that moving the clock forward by one hour during the summer months saves daylight, as people can make better use of the natural daylight in the evening.
The name is a bit of a misnomer, as it doesn’t actually save daylight. It simply shifts the time at which daylight occurs.
It is not uncommon for people to refer to it as Daylight Savings Time, which may be a result of confusion with the concept of saving time or just a common mistake. But the correct term is Daylight Saving Time.

Why Did Daylight Saving Time Start?
Daylight Saving Time (DST) was first proposed by Benjamin Franklin in 1784 as a way to save candles, but it was not widely adopted until the 20th century. The main reason for starting DST is to make better use of daylight and conserve energy.
By moving the clock forward by one hour in the summer, people can take advantage of the longer daylight hours in the evening and reduce their use of artificial lighting.
Additionally, many businesses benefit from the extra hour of daylight in the evenings, as it allows them to stay open later and generate more revenue. Some states and countries have begun to question the need for DST and whether it is still necessary, but it is still widely used around the world today.
Idea of Daylight Saving Time
The idea behind Daylight Saving Time (DST) is to adjust the clock forward by one hour during the summer months to make better use of the daylight and conserve energy. This means that during the summer, the sun rises and sets one hour later than it would if the clock were not adjusted.
The extra hour of daylight in the evenings allows people to spend more time outside, engage in leisure activities, and save energy by not having to use artificial lighting as much. Businesses also benefit from the extra hour of daylight in the evenings, as it allows them to stay open later and generate more revenue.
The idea of DST was first proposed by Benjamin Franklin in 1784, but it was not widely adopted until the 20th century. Today, many states and countries still observe DST, although some have begun to question its effectiveness and necessity.
