EXPLANATIONS BELOW
Concept note-1: -So “four score and seven years” translates to 87 years. This speech was delivered in 1863; 87 years earlier was 1776, the year that the signing of the Declaration of Independence officially declared U.S. independence and “brought forth on this continent a new nation."
Concept note-2: -Lincoln’s address starts with “Four score and seven years ago.” A score is equal to 20 years, so he was referencing 87 years ago-1776, when the Declaration of Independence was signed.
