 Several races in the United States include the "Derby" name, including the oldest, the Kentucky Derby.Other national equivalents include the Australian Derby, the New Zealand Derby, and the Tokyo Yūshun.For many years the Derby was run on a Wednesday or a Thursday and on the day huge crowds would come from London, not only to see the race but to enjoy other entertainment (during some of the 19th century and most of the 20th Parliament would adjourn to allow members to attend the meeting).
