Actually, the term "spring ahead" has always stuck in my mind, so I knew I had to set my clock forward an hour in the spring. By default, that meant to set it an hour back in the autumn ("fall back"). When I was a child, my dad told me Daylight Saving was started to give the farmers an extra hour of daylight in the summer to get their work done. That still doesn't make any sense to me. The days do not really get any just pushes the hours of daylight from one clock hour to another.

ImageFirst observed in World War I and again in World War II, Daylight Saving Time was not standardized in the United States until 1966 when the Uniform Time Act provided that any state that participated must use the federal dates. Prior to that, the states could begin and end on any dates they picked. Traditionally running from the first Sunday in April to the last Sunday in October, in 2007 a four-week extension was added in the interest of energy conservation as part of the Energy Policy Act of 2005. This year, Daylight Saving Time runs from 2 a.m. on Sunday, March 8, through 2 a.m. on Sunday, November 1. Any state may choose not to participate, or may choose to participate in only one time zone if the state is split across two zones. Arizona, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam and American Samoa currently choose to be exempt.

The extra hour of daylight on summer evenings is popular in many countries. Canada, with the exception of most of Saskatchewan, observes DST. Many of the provinces and territories also agreed to the four-week extension. The Mexican state of Sonora remains on standard time because of a shared border with Arizona Most of the rest of Mexico is on DST.

Countries in the European Union observe what they call a 'summer-time period' from the end of March to the end of October. Russia's standard time is kept one hour fast in all 11 of its time zones. Additionally, it observes DST from the last Sunday in March to the last Sunday in October. Many countries in the Southern Hemisphere maintain DST, but from October to March because that is their spring-summer. China, Japan and most countries near the equator do not observe any form of DST. Interestingly, even though Antarctica has little to gain by adopting DST, with 24 hours of daylight on many summer days, they do so to coordinate with their suppliers in Chile and other countries on DST.

Whose idea was it? Benjamin Franklin had a notion and published it in an essay in 1784, but did not seriously propose adopting the idea. A British gentleman by the name of William Willett wrote a pamplet in 1907 titled "Waste of Daylight." His original proposal was to advance time by 20 minutes on four consecutive Sundays in April and reverse the process in September. As a sidenote to my dad's comment on helping the farmers, MSN Encarta states, "In the United States during peacetime, daylight saving was a subject of controversy. Farmers, who usually work schedules determined by sun time and are therefore inconvenienced when they must conduct business on a different time basis, registered strong opposition." [2]

What does this mean to the home gardener? For those of you lucky enough to be retired (like me), maybe not much. The gardener who works during the day gets an extra hour of daylight to spend in the garden in the evening. Hopefully, some of those hours will be spent relaxing and enjoying, not just weeding and working.

Daylight Saving...'s' or no 's'? The official term is 'Daylight Saving Time', not 'Savings.' According to an article on, "Saving is used as a verbal adjective - a participle. It modifies time and tells us more about its nature..." [3]. It goes on to state that it would correctly be "daylight-saving," with a hyphen. However, 'Daylight Savings Time' is in common usage and, as such, is found in many dictionaries. Notice the 's' on the opening thumbnail. On a personal note, when I began the article, I had an 's' at the end and had to go back and edit them all out. I am sure I will continue to use the common term and my advice to you is use whatever you are comfortable with.

Whatever you call it, Don't Forget!!
If you are in the U.S. or Northern Hemisphere* where Daylight Saving Time with the four-week extension is observed, tonight (actually Sunday morning.)
Turn Your Clocks Ahead 1 Hour At 2 a.m.
*Southern Hemisphere participants should turn their clocks back
