Why does daylight savings happen?
Daylight Saving Time (or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer
How do you know whether to move your clock forward or backward?
Here's a little trick that'll help you remember:
"Spring ahead, Fall back."
What states do not go on daylight savings time?
Arizona (excluding the Navajo Nation), Hawaii, American Samoa, Guam, Puerto Rico, Northern Mariana Islands, and the U.S. Virgin Islands do not observe daylight saving time.
What is the difference in time between London England and Cairo Egypt?
Cairo is currently two hours ahead of London, England
i.e. It is now 01:13 hrs in the morning of Sunday 2nd November 2008, in Cairo, but in London it is still only 23:13 hrs the previous day, i.e. Saturday 1st November 2008.
Both countries use seasonal Daylight Saving Time, but at the moment neither of them are in DST, Cairo's DST having ceased for this year on Friday August 29th, and London's DST having ceased in the early hours of Sunday October 26th.
Does Illinois participate in Daylight Saving Time?

How does daylight saving time work?
Daylight saving time is when clocks are adjusted forward by one hour during the warmer months to make better use of natural daylight in the evenings. This practice is typically followed from spring to fall to maximize daylight in the evening hours.
What is the difference between EDT and EST?
PST and EST are time zones in North America. PST is Pacific Standard Time and EST is Eastern Standard Time. There is a difference of 3 hours between these time zones.
The Timezone Offsets of PST and EST are -8 and -5 respectively. This means that PST is eight hours behind Coordinated Universal Time (UTC), while EST is only five hours behind.
Do you really gain 1 hour of sleep with the clocks go back on Nov 2?
It is unlikely that anyone who normally wakes at a regular time would sleep for an extra hour when the clock goes back.
We do gain an hour on the day it happens. In Great Britain and Ireland our clocks went back last weekend, on Sunday morning, at 2:00 a.m.
That day had 25 hours in it, as there were officially two distinct time periods between 1:00 a.m and 2:00 a.m.
This hour compensates for the hour lost on a Sunday in April when the clocks went forward from 2:00 a.m to 3:00 a.m.

How long does it take to drive 343 miles?
It depends on how fast you drive. However, as an example, if you maintained an average speed of 65 mph, the time to drive 720 miles would be about 11 hours and 4 minutes. You would have to add time for stops, detours and other delays.
Do you gain or loose an hour sleep in the fall time change?
if you go to bed normally at 9 pm and wake up at 6 am, you would get 9 hours of sleep, so if you went to bed at 9 pm and you turn your clock back an hour when it was normally 6 am it changes to 5 am so you lose an hour for thats 8 hours of sleep. gets a bit confusing so I dont know I think you lose an hour in the morning but gain the extra hour in the evening

In 2008 when does Daylight Saving Time start in Brazil?
Brazil
Equatorial Brazil does not observe DST. Start: Third Sunday in October
End: Third Sunday in February "summer schedule", will start on October 19, 2008. At the first minute of October 19, 2008, Brazil clocks will be adjusted forward one hour in the South, Southeast and Central West regions. The time difference between the US and Brazil is smallest during the US summer, when the US is in Daylight Saving Time and Brazil is not. As of this writing on October 8, it's 7:30p in New York City and 8:30p in Rio de Janeiro. When US clocks "fall back" in the northern hemisphere fall, the time difference between New York City and Rio de Janeiro will be three hours. Today Folha Online reported that Brazil President Luiz Inácio Lula da Silva has established the third Sunday in October and the third Sunday in February as the starting and closing days for Brazil Daylight Saving Time. In years when the closing Sunday happens to be Carnival Sunday, clocks will only be adusted back on the following Sunday. Brazil Daylight Saving Time 2008/2009 will end on February 15, 2009. The time when clocks are changed is always what is called 0 hora in Brazil, that is, 12 o'clock of the night when that day starts. Brazil
