If you had trouble getting out of bed this week, it could be the hour lost to daylight savings time. But throughout history, shifting the clocks has made dollars and sense. I’m Lucas Wysocki with your Bankrate.com Personal Finance Minute.

Daylight savings time is designed to save power by shifting the hours people do business to match the rise and set of the sun. It originated when Ben Franklin, sour from waking up early, sarcastically jotted the idea in a letter, but daylight savings time wasn’t seriously considered until World War 1. The war effort demanded efficient energy use so Europe and America began falsifying clocks.

Daylight Savings Time changed throughout the 20th century, eventually leaving us with the 8-month block we know today. The time change seems to affect spending habits, personal health and power consumption, although studies are often conflicting in terms of whether the effect is positive or negative. Even America is conflicted with 47% of Americans saying they’d rather not have daylight savings time at all. For more fun financial news, visit the lighter side on Bankrate.com. I’m Lucas Wysocki.
