India, Nov. 1 -- Clocks will "fall back" an hour this weekend. Daylight Saving Time (DST) ends Sunday, November 2, at 2 am. The yearly time shift means shorter mornings, longer evenings - and one extra hour of sleep.

If you still have manual clocks at home, you will need to roll them back before bed Saturday night. Most phones and digital devices will reset automatically.

Daylight Saving Time moves clocks ahead by one hour in the spring and back by one hour in the fall. The idea dates back more than a century, per CBS News.

Germany was the first to try it in 1916, to save fuel and daylight hours during World War I. The US followed soon after, and in 1966, the Uniform Time Act made DST a national standard.
