Residents need to set a reminder to wind their clocks back one hour as daylight saving time (DST) will end this Sun., Nov. 5, at 2 a.m.

The main purpose of DST, called summer time in other places, is to make better use of daylight.

DST was first used in Canada in 1908, but was implemented country-wide in Germany on April 30, 1916, in an effort to minimize the use of artificial lighting in order to save fuel for the war effort, according to Time and Date’s website.

In the United States, DST was first used in 1918, when President Woodrow Wilson signed the fast time into law to support World War I.

Additionally, DST was referred to as War Time in the USA during World War II. It was also known as Central War Time, Eastern War Time, Mountain War Time and Pacific War Time, depending on the time zone in the United States, according to Time and Date’s website. After World War II, it was referred to as Eastern Peace Time.

At present, DST starts on the second Sunday in March and ends on the first Sunday in November.
