http://webexhibits.org/daylightsaving/c.html Rationale & original idea The main purpose of Daylight Saving Time (called "Summer Time" many places in the world) is to make better use of daylight. A poll done by the U.S. Department of Transportation indicated that Americans liked Daylight Saving Time because "there is more light in the evenings / can do more in the evenings." Daylight Saving Time also saves energy. Studies done by the U.S. Department of Transportation show that Daylight Saving Time trims the entire country's electricity usage by a significant, but small amount, of less than one percent each day with Daylight Saving Time. We save energy in both the evening and the morning because we use less electricity for lighting and appliances. Energy use and the demand for electricity for lighting our homes is directly connected to when we go to bed and when we get up. Bedtime for most of us is late evening through the year. When we go to bed, we turn off the lights and TV. In the average home, 25 percent of all the electricity we use is for lighting and small appliances, such as TVs, VCRs and stereos. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home. By moving the clock ahead one hour, we can cut the amount of electricity we consume each day. Daylight Saving Time also saves a small amount of energy in the morning when we rise. Studies show that 70 percent of all Americans rise prior to 7 a.m. during the workweek. During the summer months, sunrise is very early in the morning, so most people will wake after the sun rises. Because the sun is up, we will turn on fewer lights in our homes. Thus, we actually use less energy in the morning. In the winter, the afternoon Daylight Saving Time advantage is offset by the morning's need for more lighting. In spring and fall, the advantage is less than one hour. So, Daylight Saving Time saves energy for lighting in all seasons of the year except for the four darkest months of winter (November, December, January and February) when the afternoon advantage is offset by the need for lighting because of late sunrise. Daylight Saving Time "makes" the sun "set" one hour later and therefore reduces the period between sunset and bedtime by one hour. This means that less electricity would be used for lighting and appliances late in the day. We also use less electricity because we are home fewer hours during the "longer" days of spring and summer. Most people plan outdoor activities in the extra daylight hours. When we are not at home, we don't turn on the appliances and lights. There is a small public health benefit to Daylight Saving time. Several studies in the U.S. and Britain have found that daylight, almost certainly because of improved visibility, substantially decreases (by four times) the likelihood of pedestrians being killed on the roads.

As valid as these concerns are, would they really affect the national
economy? Since government enforces daylight savings, they have to look
at the total cost-benefit analysis. Agriculture is the only industry
that really _needs_ daylight savings, yet it only accounts for a small
fraction of the country's GDP. According to census data for 1997,
"Agriculture, forestry, and fishing" only account for $130 billion out
of a GDP of over $8 trillion, or only about 1.6% of the entire economy.
(http://www.census.gov/prod/99pubs/99statab/sec14.pdf)
So why bother? Agriculture is a strong lobby on capital hill, that's
for sure, and farming states do have a disproportionate number of
senators ...

Brian Doherty It has to do with how they interact with the rest of the world. For instance in the case of a dairy, usually the milk truck will change its arrival time whenever the clock changes. Hence unless the farmer changes his milking time he either has to pay to cool and store the milk for an extra hour (if the truck's arrival time moves back) or an extra 11 hours if the arrival time moves forward. By the way the cows don't like the change in milking time either! John Harvey

RE: Daylight savings politics
As a farm-boy from southern Manitoba, I can assure you that I didn't mind daylight savings time at all. Who the hell wants to wake up at sunrise when sunrise is 4:30 in the morning? 5:30 is far more reasonable. And, sunset at 21:30 isn't unreasonable either.

Re: Daylight savings politics
My understanding was the city-dwellers tended to be for daylight savings time since it gave them an extra hour of sunlight in the afternoon, and farmers tended to be against because it subtracted an hour from the morning, although this may be in disagreement with what is happening in Mexico if Mexico City turns out to be a more vociferous opponent than the more rural areas. Here in Japan we don't have daylight savings. The story goes that the government tried to implement it in the 1960's, but found that a lot of people ended up working one hour longer during, so they went back to year-round standard time.
