Daylight Saving Time 2016: Don't Forget To Change Your Clocks On March 13

If you already feel like you don't get enough sleep, it's about to get worse.

Daylight saving time (or daylight savings time, as some of us say) begins on Sunday, March 13 at 2 a.m. This means it's time to spring forward and move our clocks an hour ahead.

And it's not just our sleep that suffers — scientists say daylight saving time has also been linked to increased stroke risk.

Some parts of Canada don't observe the time change at all, including almost all of Saskatchewan, the northeastern corner of British Columbia, three northwestern Ontario communities, and others.

Which begs the question, why is daylight saving time even a thing to begin with? In the video above, DNews attempts to explain just that.
