KEY POINTS

Daylight Saving Time (DST)

·         DST is the practice of resetting clocks ahead by an hour in spring, and behind by an hour in autumn (or fall). During these months, countries that follow this system get an extra hour of daylight in the evening.

·         Because the spring to fall cycle is opposite in the Northern and Southern Hemispheres, DST lasts from March to October/November in Europe and the US, and from September/October to April in New Zealand and Australia.

How many countries use DST?

·         DST is in practice in some 70 countries, including those in the European Union. India does not follow daylight saving time; countries near the Equator do not experience high variations in daytime hours between seasons.

What does this system mean to achieve?

·         The rationale behind setting clocks ahead of standard time, usually by 1 hour during springtime, is to ensure that the clocks show a later sunrise and later sunset — in effect a longer evening daytime. Individuals will wake an hour earlier than usual, complete their daily work routines an hour earlier, and have an extra hour of daylight at the end.  The key argument is that DST is meant to save energy.

Countries that want DST gone

·         European Union moved to scrap the custom of DST, with the European Parliament voting 410-192. After 2021, EU member states will choose between “permanent summertime” or “permanent wintertime”. Those who choose the former will reset their clocks for the last time in March 2021; those who choose the latter would do so in October 2021.
