On what date did the Wall Street Crash begin with the market panic known as Black Thursday?

The Wall Street Crash began on October 24, 1929, the day known as Black Thursday.

Heavy selling overwhelmed the New York Stock Exchange after weeks of falling confidence and concern about highly valued shares. Five leading bankers attempted to stabilize prices by buying major stocks, but the underlying fear was not eliminated.

Black Thursday was followed by Black Monday on October 28 and Black Tuesday on October 29. The crash did not by itself cause the entire Great Depression, but it severely damaged wealth, confidence, and financial institutions.

A common mix-up is treating October 29 as the beginning of the crash. Black Tuesday was the most famous early culmination, while October 24 marks the first major panic day in the sequence.
