About

• Daylight Saving Time (DST) is the practice of turning the clock ahead as warmer weather approaches and back as it becomes colder again.
• The daylight saving time is followed in over 70 countries on various dates.
• India does not follow daylight saving time; countries near the Equator do not experience high variations in daytime hours between seasons.
  • However,people of the North east have demanded a separate time zone to make up for the loss of daylight hours due to the longitudinal breadth of India .
• Effectiveness in Modern world
  • When DST was introduced, more daylight meant  less use of costly artificial light. But modern society uses so many energy-consuming appliances all day long that the amount of energy saved is found negligible.
  • DST also disrupts the rhythm of the body clock or circadian rhythm which decreases the efficiency of the workforce.
