In October of what year did all 23 of the major world markets fall by 20% to 45% in one day, resulting in what is still known as Black Monday?

The stock market decline of 1987 is still remembered as one of the most volatile in the history of the market. On that day, the DJIA fell 508 points, which at the time was the equivalent of nearly 23%, the largest one-day percentage drop in history. The NASDAQ fell only 11.3%, but that was because the index crashed in the middle of the trading day.
