Day of the Dude is observed worldwide every March 6, celebrating the philosophy and lifestyle of Dudeism, which is inspired by the 1998 cult film The Big Lebowski. This holiday commemorates the film's release date and encourages followers to embrace a laid-back attitude, enjoying simple pleasures such as hanging out with friends, bowling, and drinking White Russians. Dudeism, founded in 2005 by Oliver Benjamin, promotes a worldview that emphasizes going with the flow and staying true to oneself, drawing inspiration from various historical figures and philosophies, particularly Taoism. Celebrations typically involve gathering with fellow Dudeists to watch The Big Lebowski and engage in bowling, although participants are free to celebrate in their own unique ways, as long as they adhere to the principles of Dudeism.
