Who doesn’t like gaining an hour every fall? Unfortunately, you have to lose it again when spring comes around. But is daylight saving time capitalized?

Is Daylight Saving Time Capitalized?

According to the US Government Publishing Office style guide, the phrase “daylight saving time” should not be capitalized. They even say that the abbreviation of daylight saving time d.s.t. should be lowercase.

However, it is a commonly accepted practice that the entire phrase, as well as the acronym, are capitalized such that they read “Daylight Saving Time” and “DST.”

Is It Spelled Daylight Saving Time or Daylight Savings Time?

The grammatically correct way to spell “daylight saving time” is without a “s” after “saving.” Some dictionaries say it is ok to say “savings,” but the generally accepted standard is to leave “saving” singular.

Occasionally people also try to may “daylight” plural or possessive such as “daylights saving time”, but it too should be singular.

History of DST (Daylight Saving Time)

DST or Daylight Saving Time is implemented to make better usage of daylight and save energy. During part of the year, a time change measure is used by setting the clocks one hour in advance of standard time. Around 40% of countries worldwide now use DST to conserve energy.

In 1916, the initial countries to use DST were Austria and Germany. The citizens of Port Arthur in Ontario started the first DST period by turning forward an hour on their clocks on July 1, 1908. Other Canadian locations soon followed the same action. Daylight saving time was implemented by Regina in Saskatchewan on April 23, 1914. The cities of Brandon and Winnipeg in Manitoba followed the same on April 24, 1916.

However, the idea of DST was not known and implemented globally until it was introduced by Germany in 1916. Two years into World War 1, on April 30, 1916, German Empire’s clocks were turned an hour in advance of standard time. It was to conserve fuel for war by minimizing the usage of artificial lighting. The idea of DST was followed by France, United Kingdom, and other countries in just a few weeks. After World War 1, most of the countries returned to standard time and it made its return in most European countries on the succeeding World War.
