Historical dates are specific days that mark significant events in the past. These dates help us understand the timeline of human history and the development of societies. For example, the signing of the Declaration of Independence in the United States on July 4, 1776 is a crucial date that signifies the country's quest for freedom. Understanding historical dates allows us to connect with important moments, such as the fall of the Berlin Wall on November 9, 1989, which symbolized the end of the Cold War. These dates serve as reference points for studying the impact of events on culture, politics, and society throughout history.
