Clocks spring forward for daylight saving time this weekend

This weekend, most Canadians will roll their clocks forward for daylight saving time. The "spring forward" officially starts Sunday at 2 a.m. and we will once again lose an hour of sleep. 

Here are some facts to consider during your extra hour of wakefulness:

- In 1908, Thunder Bay became the first location in Canada to use DST. 

- Not all places in Canada observe DST, including most of Saskatchewan, some communities in British Columbia, Northwestern Ontario, Quebec and Nunavut.

- Daylight savings time is used in only about 70 countries worldwide, primarily in North America and Europe. 

- Germany became the first country to introduce DST when clocks were turned ahead one hour on April 30, 1916 in an effort to save energy during the First World War. 

- Not all countries follow the one hour adjustment. In Lord Howe Island, Australia, clocks are set only 30 minutes ahead from LHST (UTC+10:30) to LHDT (UTC+11) during DST.
