Yeah, it's the Friday right after Thanksgiving which is always on Thursday. The term 'Black Friday' is derived from accounting. People in the U.S. kept books in two colors: red and black. They use red ink when the business is in debt. However, the Friday after Thanksgiving has traditionally been the day where the retail business actually starts earning money. So, the accountants would balance out that day's sales and start using black ink at the end of it. Hence, Black Friday.
