6 facts about daylight saving

Clocks move forward one hour on Sunday, March 11 at 2 A.M., but that’s not the only information that might be useful to know.

Wisconsin approved to set Wisconsin on Daylight Saving Time (DST) by law on the April 2, 1957 ballot.

Daylight saving is not plural

Daylight savings is a misspelling, but is more commonly used than the correct term, daylight saving.

Not all states observe it

Arizona, Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands do not spring ahead. Prior to 2006, part of Indiana did not observe DST, but to avoid confusion, a law was passed to require all of Indiana to use DST.

It was introduced to save energy

The idea started during World War I to make daylight hours in the evening longer. If the sun would set later, households would spend less time with lights on, which would save money on electricity. To this day, it’s not clear if daylight saving actually saves money on electricity because of the increase of air conditioning and gas consumption.

Daylight saving has a few alternative names

Some popular synonyms for daylight saving are spring ahead and spring forward. These two synonyms can help you remember what to do with your clock, which is to move it one hour ahead.
