About National Sleepover Day
Sleepovers are a quintessential part of the youth culture, and, therefore, a special day has been designated as the National Sleepover Day to celebrate the idea.
We only wish this incredible national day fell on a day that isn’t a school night! However, if you are an adult who pays your own bills, you can have people sleep over whenever you want. Invite your besties over for some classic slumber party shenanigans, and party it up until you crash from a sugar-high. Just be prepared to face your boss the next morning.
This day began as an event held by the Cosmopolitan magazine and the Bare minimal brand in New York on May 9th 2017. It obviously tapped into a need to celebrate this American tradition as it is now celebrated across the country.
