Daylight saving time is a practice that involves moving the clocks by one hour during the warmer months of the year. The main behind this adjustment is to make better use of natural daylight in the evenings, which can reduce the need for artificial lighting and lower energy .

Critics argue that the twice-yearly clock change disrupts sleep patterns and provides only minor energy savings, while supporters point to benefits for outdoor leisure activities and retail businesses.
