National Napping Day was founded in 1999 by Dr. William Anthony, a Boston University professor, and his wife Camille Anthony. The couple recognized that the shift to Daylight Saving Time often leaves people sleep-deprived and less productive.

The day was first promoted through local media and quickly gained national attention, resonating with many who struggle with the spring time change.
