does every country in the world put their clocks back or is it just europe?

Answer 1

More than one billion people in about 70 countries around the world observe DST in some form. Here are interesting facts about some of these countries:

Most of Canada uses Daylight Saving Time. Some exceptions include the majority of Saskatchewan and parts of northeastern British Columbia. In the fall of 2005, Manitoba and Ontario announced that like the United States, they would extend daylight time starting in 2007. The attorney general of Ontario commented that "it is important to maintain Ontario's competitive advantage by coordinating time changes with our major trading partner, and harmonizing our financial, industrial, transportation, and communications links." Other provinces have indicated that they may also follow suit.
It wasn't until 1996 that our NAFTA neighbors in Mexico adopted DST. Now all three Mexican time zones are on the same schedule as the United States.
Also in 1996, members of the European Union agreed to observe a "summer-time period" from the last Sunday in March to the last Sunday in October.
Most countries near the equator don't deviate from standard time.
In the Southern Hemisphere, where summer arrives in what we in the Northern Hemisphere consider the winter months, DST is observed from late October to late March.
Three large regions in Australia do not participate in DST. Western Australia, the Northern Territory, and Queensland stay on standard time all year. The remaining south-central and southeastern sections of the continent (which is where Sydney and Melbourne are found) make the switch. This results in both vertical and horizontal time zones Down Under during the summer months.
China, which spans five time zones, is always eight hours ahead of Greenwich Mean Time and it does not observe DST.
In Japan, DST was implemented after World War II by the U.S. occupation. In 1952 it was abandoned because of strong opposition by Japanese farmers.

Answer 2

No, it depends on the country.
Many European countries do have a daylight savings time policy, as does the United States and many others like Brazil. Others opt not to have a daylight savings time policy like in the case of Argentina.

Answer 3

Well, here In the United States we do have a daylight savings time were we put our clocks ahead one hour, but it is not the whole country. I've heard of several states that do not. here in Florida unfortunately we do.

Answer 4

The clocks go ahead 1hr in the Spring 1hr back in the Fall.
Some parts of Canada did

Answer 5

you mean daylight saving time (DST)?

Once I devoleped a program with a zoneinfo database - long headache.

Australian use DST and the government changed the 2006 DST

Amis have it also.
In the 1970s the U.S. Law Enforcement Assistance Administration (LEAA) found a reduction of 10% to 13% in Washington, D.C.'s violent crime rate during DST.

You can hack your DST by your own:
DST information is stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\, under the TZI registry value. In Windows XP and Windows Server 2003 the information comes from the time zone database stored in the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\. When the rule changes an update needs to be applied

Answer 6

Daylight savings time was invented by, or at least attributed to, Benjamin Franklin and most places have adopted it. But not everyone. Even in the US, Indiana and Arizona have counties that won't use it.

Answer 7

We put our clocks forward at the end of this month on the last Saturday

Answer 8

most countries above the equator do... there is no need to below the equator, since the light is pretty much the same year round... here is a list:
