When Is Spring Forward Time Change. When does daylight saving time begin again? On saturday night, clocks are set forward 1 hour (i.e., losing one hour) to “spring forward.”.
Daylight saving time begins on sunday, march 9, 2025, at 2:00 a.m. The second sunday in march is when daylight saving time begins in most areas of the us, so in 2024 we will “spring forward” one.
