If you still haven't bounced back from this weekend's springing forward, good news.

Monday is not only Pi Day, it is also National Napping Day.

According to Days of the Year, the unofficial sleeping holiday gives anyone who is still feeling the effects of losing an hour of sleep Sunday morning the opportunity to get some quick shut-eye during a catnap. 

Dr. William Anthony, a Boston University professor, came up with National Napping Day in 1999, Huffington Post reported.

He wanted to encourage people to make naps a part of everyone’s lives to help them be healthy and productive.

Anthony said they chose the Monday after daylight saving time begins because people were already in nap mode after losing that hour of sleep, Shape reported.

And if Napping and Pi days aren't for you, March 14 also marks National Potato Chip Day, National Children's Craft Day and National Learn About Butterflies Day, according to National Day Calendar.
