If you're not caught up on your sleep then Saturday night isn't going to help, as clocks go forward an hour.
It's "Daylight Saving Time" once again, so Minnesotans will lose an hour at 2 a.m. on Sunday, which they will get back this fall.
On the downside it'll be darker when you wake up, but on the upside the light will stay longer into the evening – perfect for enjoying the unseasonably warm weather across the state.
As Al.com explains, the idea of Daylight Saving Time was first mooted in the time of Benjamin Franklin, but it wasn't until World War I it was implemented to save fuel by reducing the need to use artificial lighting.
It then stopped at the end of the war, but was resumed again during World War II only to stop again three weeks after the end. It only became standard in the U.S. in 1966, when the Uniform Time Act was passed by Comgress.
Hawaii, "most" of Arizona, and American territories don't observe DST.
Fortune points out that the idea the move to DST was firmly opposed by the farming lobby, which argued it left them with less sunlight to get crops to market while cows didn't adjust well to the time shift.
The energy savings are not huge, with the Department of Energy says it saves about 0.5 percent electricity, whereas a California Energy Commission study in 2007 found savings of only of 0.2 percent – with a 1.5 percent margin of error.
If you find yourself not your usual self at work on Monday, you're not alone. Studies have found there's a productivity loss costing the nation around $434 million the day after DST.
The Verge, meanwhile, has referred to DST as "hot garbage," arguing that the supposed energy saving benefits don't carry any weight, and shifting the time does far more damage by increasing fatigue and potentially increasing the danger of serious incidents caused by sleep deprivation.
