If you have ever wondered, four score and seven years ago is how many years, the short answer is 87 years. A score means 20 years, so four score means 80 years, and four score and seven adds seven more, giving 87 in total. The phrase comes from the opening line of the Gettysburg Address, delivered by Abraham Lincoln in 1863, where it points back 87 years to 1776, the year of the Declaration of Independence. This guide explains the maths step by step, the history behind the phrase, why Lincoln chose such old-fashioned wording, and how to work out similar phrases whenever you meet them.
Four Score and Seven Years Ago Is How Many Years: The Direct Answer
To answer four score and seven years ago is how many years with full clarity, break the phrase into its parts. Four score means four groups of 20, which is 80. Seven years means seven single years. Add them together: 80 plus 7 equals 87. The phrase therefore means 87 years ago. It is a poetic way of saying nearly nine decades earlier, and it sounds grander and more formal than simply saying 87 years ago, which is part of why Lincoln used it.
Lincoln delivered the Gettysburg Address on 19 November 1863, at the dedication of a soldiers cemetery at Gettysburg, Pennsylvania, after a major Civil War battle there. Counting back 87 years from 1863 gives 1776. That was the year the American colonies declared independence from Britain. Lincoln was therefore not picking a random number. He was linking the cemetery dedication in 1863 to the founding moment of the nation in 1776, and reminding his listeners that the soldiers being honoured had died in a struggle over what that founding promise meant.
The maths is simple, but the effect is powerful. By saying four score and seven years ago instead of in 1776, Lincoln made his audience do a small piece of mental arithmetic and feel the distance of time. Eighty-seven years is longer than a single lifetime for most people in 1863, so the phrase also suggested that the nation was no longer new. It had lasted long enough to be tested, and the test was happening in the Civil War itself.
Four Score and Seven Years Ago Is How Many Years: What a Score Means
The key to four score and seven years ago is how many years lies in the word score. A score means 20. The word comes from an old counting practice: people would cut a notch, or score, on a tally stick for every 20 items counted. Over time, score became a standard word for a group of 20, much as a dozen means 12. You may have met the word in the famous line about threescore years and ten, which means 70 years: three groups of 20, which is 60, plus ten.
Score is rarely used for counting in everyday modern English, which is why the phrase can puzzle readers today. In Lincoln’s time, however, score was still familiar from the Bible, from older literature, and from everyday speech in some communities. Listeners in 1863 would have understood four score at once, or with only a moment of thought. Modern readers need the translation, but once you know that a score is 20, the whole phrase opens up.
Score Maths in Plain Steps
Here is the working in the clearest possible form. One score equals 20 years. Two score equals 40 years. Three score equals 60 years. Four score equals 80 years. Add the seven years named separately, and four score and seven equals 87 years. If you meet a similar phrase, follow the same method: multiply the number before score by 20, then add any extra years named after it.
Other Score Phrases You May Meet
Threescore years and ten means 70 years, as noted above. Fourscore years means 80 years. Threescore and ten is the most famous example after Lincoln’s phrase, because it appears in a well-known biblical passage about the span of human life. Seeing these phrases together helps confirm the pattern: score always means 20, and the extra number is added afterwards.
The Gettysburg Address and 1776
The Gettysburg Address is one of the shortest and most studied speeches in American history. Lincoln spoke for only a few minutes, yet his words reframed the Civil War as a test of whether a nation founded on the idea that all people are created equal could endure. The opening line does much of that work. By reaching back to 1776, Lincoln reminded listeners that the nation was conceived in liberty and dedicated to equality, in his famous wording. The soldiers at Gettysburg, he argued, were giving their lives to keep that founding promise alive.
Counting back 87 years also matters because it places the founding just beyond living memory in 1863. No one alive in 1863 had been an adult in 1776. The founding generation had passed away. Lincoln was therefore speaking to a generation that had inherited a nation it did not found, and asking whether that generation would preserve it. The phrase four score and seven years ago carries that sense of inheritance: a long time has passed, the founders are gone, and the responsibility now belongs to the living.
The speech was delivered at a cemetery dedication, which shaped its tone. Lincoln did not give a long battle report or a political argument in detail. He spoke about dedication, sacrifice, and the unfinished work remaining for the living. The opening time phrase sets that tone at once: it is solemn, measured, and historical, lifting a local ceremony into a national reflection on founding, war, and future.
Why Lincoln Chose This Wording
Lincoln chose four score and seven years ago for several reasons, and each reveals something about his skill as a speaker. First, the wording sounds biblical and timeless. Score appears in older English and in the King James Bible, so the phrase gave the speech a gravity that a plain date would not carry. Second, the wording is rhythmic. Four score and seven years ago has a rolling, memorable cadence that suits spoken delivery and helps listeners remember the line.
Third, the wording invites the audience to participate. A listener must convert score into 20 and add seven to reach 87, then connect 87 years back from 1863 to 1776. That small mental effort makes the connection feel discovered rather than merely stated. Fourth, the wording avoids the bluntness of a number. Saying 87 years ago is clear, but saying four score and seven years ago feels like history speaking, which matched the solemn occasion.
Finally, the wording connects Lincoln to a long tradition of English public speech. By using an older counting word, he placed his short address in a lineage of speeches and writings that treated national life in terms of generations and ages, not only in terms of dates. That choice helped a two-minute speech feel like a document for the ages, and history has largely agreed with that judgement.
Counting Back From 1863: A Worked Example
Many readers ask not only how many years the phrase means, but how to check the year it points to. The method is simple subtraction. Start with the year of the speech, 1863. Subtract 87 years. Break the subtraction into easy steps: 1863 minus 80 equals 1783, and 1783 minus 7 equals 1776. The result is 1776, the year of the Declaration of Independence. This check confirms that the phrase and the history line up exactly.
You can use the same method for any similar phrase. Identify the starting year, work out how many years the phrase means, and subtract. If you are counting from a different starting year, the target year will change, because the phrase means a length of time, not a fixed year. Four score and seven years ago from today would point to a different year than it did in 1863, but the length of time, 87 years, stays the same. That distinction between a duration and a date is worth keeping in mind whenever you read historical speeches.
Students often find it helpful to write the steps out, as in the table below, rather than trying to hold all the numbers in mind at once. The table also shows how the same phrase can be read as a duration, as a subtraction, and as a historical reference, all at the same time.
| Step | Working | Result |
|---|---|---|
| Value of one score | 1 score | 20 years |
| Value of four score | 4 times 20 | 80 years |
| Add the extra years | 80 plus 7 | 87 years |
| Count back from 1863 | 1863 minus 87 | 1776 |
| Historical meaning | Year of independence declared | Founding of the United States |

Common Mistakes When Reading the Phrase
The most common mistake is to read score as 10, which would give 47 years instead of 87. That error comes from confusing score with a decade, or from guessing without checking the old meaning. A second mistake is to treat four score as 40, by confusing four score with four tens. A third mistake is to add the numbers incorrectly, for example by adding four and seven first and then multiplying, which gives the wrong total. The correct order is to multiply first: four times 20 equals 80, then add seven.
Another mistake is to assume the phrase points to a fixed year in every use. It does not. It points to a duration of 87 years before whatever moment the speaker is describing. In the Gettysburg Address, that moment is 1863, so the target is 1776. In a different speech, the same phrase would point elsewhere. Keeping duration and date separate prevents this confusion.
A final mistake is to modernise the phrase too quickly and lose its tone. Translating it as 87 years ago is accurate, but it misses the solemn, biblical flavour that Lincoln intended. Good historical reading keeps both: the clear modern meaning for understanding, and the original wording for feeling how the speech sounded to its first listeners.
How Teachers and Students Use the Phrase
Teachers often use four score and seven years ago as a doorway into the Gettysburg Address, because it combines maths, vocabulary, and history in a single line. A student who works out 87 years has practised multiplication and addition. A student who learns that score means 20 has met an older English word in context. A student who subtracts 87 from 1863 to reach 1776 has connected a speech to a founding document. That triple learning is why the line appears in so many lessons.
The phrase also works well for discussions about language change. Words enter and leave everyday use, and score is a clear example: once common, now mostly literary or historical. Discussing why Lincoln could use it confidently in 1863, while modern readers need a gloss, helps students see language as something that changes over time, not as a fixed list of words.
For memorisation, the phrase helps too. Its rhythm makes the opening of the Gettysburg Address one of the most quoted lines in English. Students who remember four score and seven years ago often remember the whole opening sentence, and from there the rest of the short speech becomes easier to learn. Rhythm, meaning, and history reinforce each other, which is a mark of strong writing.
