You really only need to know a few dates by heart. The first is 1776 when we made our claim to independence. The second is 1789 when we ratified the Constitution. You should also know the dates of the Civil War (1861-1865) and World War II (1941-1945). I would include September 11, 2001 as an important date on the timeline.
