October 24, 1929 is called Black Thursday, and October 29, 1929 is referred to as Black Tuesday. When talking about financial markets the term "black" typically means a disastrous day in the world of finance. On Black Thursday the trouble started, and on Black Tuesday the value of stocks dropped by about 13% on that one day.
Black Tuesday is the day most historians use as the beginning of the Great Depression Throughout history there have also been days referred to as "Black Monday" or "Black Friday" where the financial markets have also performed poorly In times past, people wore black clothes when a family member died and draped black cloth on their house door, and everyone wore black to a funeral. So when they said Black Thursday or Black Tuesday, they meant they felt like they were at a funeral for the stock market There is also a good 'black' day. At Christmas shopping time, there is a day when the stores finally get out of the 'red' (losses were written in red ink in old account books) and get into the 'black' (profits were written in black ink).
