Correction: An earlier version of this article muddled the time changes in the U.K. and Australia (meaning: even we got confused by Daylight Saving Time!). Thanks to BlogPost reader Rodney for providing us with clearer language.

Confused? So are plenty of people. Every year when the clocks fall back or spring forward an hour, people wonder what the practice actually does. A time management coach, CGP Gray, decided to take a look at Daylight Saving Time and the confusion surronding it.

He created a short film explaining if the venture is actually time efficient. It’s a brilliant piece chock full of information. A few surprisig trivia points:

●Germany was the first to put it into practice to save coal for World War I.

●The man who invented it wanted more time in the summer to catch bugs for his collection.

● There is an estimated $480,000,000 lost in productivity the first week after the change.

● There is a spike in heart attacks and suicides the Monday after the time change.
