Daylight Saving Time-DST

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.
