Spring forward, fall back” is one of the little sayings used to remember which way to set your watch. You set your clock forward 1 hour in the spring when DST starts (= lose 1 hour), and back 1 hour when DST ends in the fall (= regain 1 hour). When local standard time is about to reach Sunday, March 10, 2019, 2:00:00 am clocks are turned forward 1 hour to Sunday, March 10, 2019, 3:00:00 am local daylight time instead. Sunrise and sunset will be about 1 hour later on Mar 10, 2019 than the day before. There will be more light in the evening.
