Well it's that time of year again... when the clocks go forward an hour. For those of us in Britain, ours already have, but for those in Canada or the US then they have another week to wait... until next year.

In Britain (and the rest of Europe that follows DST), the clocks go forward an hour on the last Sunday of March, and back an hour on the last Sunday in October. (This will not be changing!!)

In Canada and the US things are a little more complicated - mainly because the countries are so vast and they span many timezones, with some states/provinces/territories covering 2 timezones. In spite of this, the majority of the country does follow DST, and go forward an hour on the first Sunday in April and go back on the last Sunday in October. In 2007, however, this will all change!

Beginning in 2007, the United States will start DST on the second Sunday in March, and change back to standard time on the first Sunday in November. Indiana should have formally adopted DST in 2006, although which timezone your county falls in might've changed from EST to CST.

In Canada, the governments of Ontario, Manitoba, Quebec, Prince Edward Island, New Brunswick and Alberta have pledged to change their daylight saving rules to match the US. From 2007, their DST will also start on the second Sunday of March, and return to standard time on the first Sunday in November.

Hopefully all the confusion in the US and Canada will have been sorted out by the time March 2007 comes along, otherwise there will be a lot of very disoriented people wandering around not knowing what the hell the time is!

A good resource for more information about the changes in DST coming up is the Daylight Saving Time article on Wikipedia.
