Daylight Saving Time

See http://www.phrases.org.uk/bulletin_board/44/messages/944.html for this discussion.

huh?

you mean why do we have daylight saving?

if that is the question, then in my opion, i like daylight saving because it can save electricity and parents can spend more time with their kids near the beach or something if they work late since there is still daylight out there

No, Johannesburg does not participate in daylight saving time. The city follows South Africa Standard Time (SAST) throughout the year.

If your clocks are on Daylight Saving Time (DST), a.k.a. Summer Time, on the weekend when Standard Time resumes, make the time one hour earlier. A popular mnemonic device for remembering which direction to adjust is "spring forward; fall back". On some older clocks you have to advance the time 11 hours.

For example, in North America, every time zone of every country that observes DST except Cuba begins and ends DST at 2:00 AM. That means that on the 1st Sunday of Nov., or on the last Sunday of Oct. in most of Mexico, one minute after 1:59 AM is 1:00 AM. On the east coast of the U.S., one minute after 1:59 AM EDT is 1:00 AM EST, on the U.S. west coast, one minute after 1:59 AM PDT is 1:00 AM PST, and so on. In Europe, every country that observes Summer Time does the time changes at the same time (1 AM UTC), no matter which time zone they're in. So on the last Sunday of Oct., when universal time changes from 00:59 to 01:00, most of Europe changes from 02:59 CEST to 02:00 CET, eastern Europe changes from 03:59 EEST to 03:00 EET, and western Europe changes from 01:59 WEST, BST or IEST (Irish Summer Time) to 01:00 WET or GMT.

There is currently only one place in world where the time change for DST is not one hour. On Australia's Lord Howe Island clocks are adjusted forward one half hour at the beginning of DST (on the first Sunday of October) and turned back one half hour at the end of DST (on the first Sunday of April). Because the southern hemisphere's summer is in the opposite half of the year from the northern hemisphere's summer, the southern hemisphere observes DST during the opposite half of the year from the northern hemisphere.

Aside from 9 Feb 1942 to 30 Sep 1945, when all of the United States, including the Territories of Alaska, Hawaii, and Puerto Rico, was on continuous daylight saving time (DST) due to World War II, Alaska began the annual clock changes in 1969. DST in the United States began on 27 Apr that year. Annette Island was allowed to stay on Pacific Standard Time (UTC-8) year-'round when 99.6% of Alaska was consolidated into one time zone, AKST/AKDT or UTC-9/UTC-8, on 30 Oct 1983, but they switched to Alaska Time, including the annual clock changes, in 2016.

Not any more. When it was first introduced, it was done so because public street lighting wasn't as effective as it is now. These days, with modern lighting - there's no real need to switch to daylight saving time.

The hope is that we save energy - since there's less of a need to switch on the lights if natural light will do . [Studies have shown the electricity conserved on the new schedule is actually pretty nominal .]

To make everyone get up an hour earlier during the spring, summer, and early fall when there is more daylight during both morning and evening hours as not to waste all of those extra morning hours in bed, while still pretending that we are getting up at the same time by setting our clocks an hour fast so that most of us don't notice.

Someone has to stop it and kinda wind it on. The gravity stoppers, that allow the hands to move every 2 seconds are removed and the clock hands move quickly. When the correct time is reached, the gravity stops on the pendulum is replaced and the hands are only allowed to move at 2 second initials again.

Day and night varies throughout the year depending on the angle of the sun and the axis of the earth. The further you are from the equator the greater the differences. If you live on the equator the difference is virtually nil.

Everywhere north of the Arctic Circle and south of the Antarctic Circle has at least one day per year on which the sun does not set. The closer you get to the poles, the more days without a sunset there are. Six months later, those places have multiple consecutive days on which the sun never rises.

The formula for determining potential difference is V = W/q, where V represents potential difference (in volts), W is the work done moving a charge (in joules), and q is the amount of charge moved (in coulombs).

On the equinox, there is 12 hours of daylight and 12 hours of night everywhere except the poles. At the poles, the equinox means that the sun is either rising for the first time in 6 months or setting for the first time in 6 months.

Daylight Saving Time was first implemented in 1916, during World War I.

No, Tennesse didn't go on daylight saving time until 1970s.

the farmers invented it for crop things.

In "Daylight Saving Time," "Daylight Saving" is being used as an adjective - as in time that is saving daylight. "Daylight Savings" would be a noun itself, and makes little sense applied as an adjective in this context.

Many people use the word savings, not knowing the correct way to say it.

Edit; "Daylight Saving" time.

Yes. Spain, like the whole of Western Europe (and possibly all of Europe) puts the clocks forward at 2am on the last Sunday in March, and back again at 3am on the last Sunday in October. Spain is GMT +1, so is EST +6.

Alabama has observed daylight saving time every year since 1918, including year-round from February, 1942 until September, 1945.
