look up any word, like hipster:
J.T. Day is celebrated annually on the 10th of September. The weekend before (or of, in the event the 10th is a weekday) and the weekend after are also celebrated. Activities include drinking Justin Timberlake's tequila, 901; listening to Justin Timeberlake records; dancing; wearing bow ties; and enjoying life more than anyone else.

The holiday is officially called Two Weekends of J.T. Day. However, it is generally shortened to just J.T. Day.

It was first celebrated in Lawrence, Kansas in 2006.
