The opposite of Daylight Savings Time (DST) is Standard Time. While Daylight Savings Time involves setting the clocks forward by one hour to extend evening daylight during the warmer months, Standard Time is the regular time observed throughout the rest of the year when clocks are set back, providing more daylight in the mornings and less in the evenings.
During DST, which typically starts in the spring and ends in the fall, clocks are moved forward an hour. When the clock is set back an hour in the fall, we return to Standard Time. This change is essentially about how we manage our time to make better use of daylight during specific seasons.
