In the U.S., 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, 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. Daylight saving time lasts for a total of 34 weeks (238 days) every year, about 65 % of the entire year.
