National Day Calendar

There are several claims to National Hangover Day. A joking, one-off reference comes in a 1993 review of a concert by the jam band Phish. Urban Dictionary includes an entry for National Hangover Day for January 1st in 2005, along with many humorous variations in the late 2000s (e.g., “Every day since I started college.”)


In December 2009, Warner Bros. marketed the DVD release of its hit comedy film The Hangover by declaring January 1st National Hangover Day. This event corresponds with the greatest search interest in National Hangover Day on Google.

The National Day Calendar, a popular website which tracks of all those hashtag holidays you see around the internet, added National Hangover Day in 2015. It says it was dreamt up by two friends who observed that many of their peers year too busy nursing headaches on January 1st to kick off their New Year’s resolutions.
