Why, you may ask, do we confuse ourselves this way? I thought it is to enable children to walk to school (or wait at bus stops) in daylight, rather than in darkness. After googling "daylight savings time history" I learned that it is also a way to save energy, and that the idea first came from U.S. Founding Father Benjamin Franklin. For more information, see the sidebar for a link to an interesting Daylight Savings site.
Enjoy your extra hour, and don't be late for class on Tuesday!
