If springing forward for daylight saving time has you feeling drowsy, grumpy, or unproductive, then National Napping Day was literally made for you. Created in 1999 by Boston University professor William Anthony, this annual event is observed on the day most Americans are "nap-ready." So, take a cue from this African leopard and find a comfy place to catnap.
