Human: I need help understanding the concept of daylight savings time. Can you explain it? Assistant: 
Daylight Saving Time (DST) is a system used to move the clocks forward an hour during the summer months to take advantage of the increased daylight hours. During DST the sun rises and sets later, so people have more light in the evenings to enjoy outdoor activities. During the winter months, clocks are set back an hour so that people can get up earlier in the morning and have more natural light when they go to school or work.
