At 2 AM in the morning those living in an area where Daylight Savings time is observed should set their clocks forward one hour on this day. The companion to this observance, Daylight Savings Time Ends, is observed on the last Sunday in October.

"Spring forward, and Fall back" is a mnemonic used by many people to remember whether to move your clock forward or backward.

The Start and End of Daylight Savings Time is observed in both the US and Canada on the same day. In the US, all states and territories observe it except Arizona, Hawaii, Puerto Rico, the US Virgin Islands, American Samoa, and most of Indiana. Once the clock is set forward, those that are normally on Eastern Standard Time will be on Eastern Daylight Time, those on Central Standard Time will be on Central Standard Time, etc.

Daylight Savings Time was first proposed by Benjamin Franklin in the 1700s. Franklin developed his plan as a way for colonial Philadelphians to reduce the use of candles.

In the US, Daylight Savings Time was first instituted nationally from 1918 to 1919 to save resources during War World One. After the war, Daylight Savings Time was repealed. Some states and municipalities continued to observe it, others did not. Daylight Savings Time was instituted a second time nationally from 1942 through 1945 to save resources during War World Two. Again, it was repealed after the war, and a hodgepodge of states and municipalities continued to observe it.

In 1966, Canada and the US standardized the observance of Daylight Savings Time in and across both countries. Today most states, providences, territories, and municipalities observe Daylight Savings Time as defined in the Uniform Time Act adopted in 1966.
