Historical dates are specific days or periods that mark significant events in the past. These dates help us understand the timeline of human history, such as the signing of the Declaration of Independence on July 4, 1776, or the fall of the Berlin Wall on November 9, 1989. By studying these dates, we can learn about the causes and effects of important events. Knowing historical dates is essential for understanding how societies have evolved over time. They provide context for major developments, like the start of World War I on July 28, 1914, or the first moon landing on July 20, 1969. These milestones shape our collective memory and influence current events.
