The purpose of DST is to take advantage of longer daylight hours during the summer months, potentially reducing energy consumption and increasing outdoor activities.

By advancing clocks in the spring, sunrise and sunset times become later, providing more daylight in the evening. This can encourage people to spend more time outdoors, engage in recreational activities, or complete tasks that require natural light. However, DST also has potential drawbacks, including sleep disruption, increased risk of traffic accidents, and health effects for individuals with certain medical conditions. Despite these drawbacks, DST remains a widely practiced measure in many countries to maximize the benefits of natural daylight during the summer.
