The Buy Nothing Day (BND) is an international day of protest against consumerism observed by social activists. Typically celebrated the Friday after American Thanksgiving in North America and the following day internationally, in 2022 the date is November 25. It was founded by Vancouver artist Ted Dave and subsequently promoted by Adbusters magazine, based in Canada.
Various gatherings, shenanigans, and forms of protest have been used on Buy Nothing Day to draw attention to the perceived problem of over-consumption. The first Buy Nothing Day was organized in Vancouver in September 1992 "as a day for society to examine the issue of over-consumption." In 1997, it was moved to the Friday after American Thanksgiving, also called "Black Friday", which is one of the 10 busiest shopping days in the United States.
