Daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time. With a mnemonic word play referring to seasons, clocks “spring forward and fall back”—that is, in springtime the clocks are moved forward from 2:00 a.m. to 3:00 a.m., and in fall they are moved back from 2:00 a.m. to 1:00 a.m.
