Daylight

saving time Daylight saving time (DST) is an energy-saving measure that changes the time of the clock during certain periods of the year. It is usually observed by advancing the clock forward during spring when there is more daylight, and by turning the clock back in autumn when there is less light. By doing so, DST helps to reduce energy consumption by increasing the amount of daylight available in the evening, when people tend to use their lighting and electronic devices more. DST can help to reduce the pressure on energy sources and conserve natural resources by reducing the need for electricity for lighting and appliances. Additionally, DST can have positive economic benefits by helping to reduce energy costs and encouraging people to socialize and shop in their local area during the evenings.
