What is ‘Daylight Saving Time’?

Daylight Saving Time (DST), also known as summertime in some countries, is a mechanism for saving energy and involves resetting clocks.

Daylight Saving Time (DST)

Daylight Saving Time (DST) is the practice of pushing clocks forward (usually one hour) during spring and setting clocks back one hour in autumn to return to standard time. Thus, in some countries the clock time is changed twice a year.

Purpose of Daylight Saving Time (DST)

In summer, the sun rises earlier and sets later, thus the daylight hours will be longer. Thus if the clocks are further in the summer months, there will be more useful hours of daylight. People will start their day one hour earlier and also complete their daily work routine one hour earlier. Therefore, there will be a longer evening day for activities or an additional hour of daylight, which ensures less consumption of electricity and other forms of energy.

In the fall, as daylight hours shorten, the clocks are set back to standard time.

DST Compliant Countries

Currently, DST is observed twice a year by around 70 countries. In the US, except for 2 states, all other states follow the Daylight Saving Time (DST) practice and change their clock twice a year. All European Union (EU) countries and many other European countries also follow DST. Outside Europe, it is followed by countries such as Iran, Mexico, Argentina, Paraguay, Cuba, the Levant, New Zealand, parts of Australia and Haiti.

Daylight Saving Time History
