Apostrophe Before or After Year: What's the difference & usage? 2026

Have you ever wondered whether to put an apostrophe before or after a year? This small punctuation mark can cause big confusion, especially when writing dates in sentences or on social media. Many people are unsure whether to write ‘90s, 90’s, or 1990s, and mistakes often slip through unnoticed. Understanding the correct usage is important because it ensures your writing looks professional, clear, and grammatically correct.

The confusion is even more pronounced for writers working in both British and American English. While the rules are largely similar, subtle differences exist, and these can affect how your audience perceives your writing. Using an apostrophe incorrectly can make your text look sloppy, or worse, change its meaning entirely.

In this article, we’ll break down everything you need to know about apostrophes and years. From the correct placement to common mistakes, tips, and examples for both UK and US readers, this guide will make you confident in using apostrophes around years.

Quick Answer

The general rule is: do not use an apostrophe when referring to a decade or a year in plural form. For example, the correct form is:

1990s (not 1990’s)
2020s (not 2020’s)

Use an apostrophe only when you are showing possession or omission of numbers. For example:

Possession: The year’s events were historic. ✅
Omission: Back in the ‘90s, life was different. ✅

In short: apostrophe before a year is for omitted numbers, and apostrophe after a year is usually incorrect for plural decades.

Meaning of the Correct Form

Using the correct form of a year with or without an apostrophe depends on context. Let’s explore this in detail.

1. Plural of a Year (No Apostrophe)

When talking about a decade, you simply add s to the year:

1990s – Refers to the entire decade from 1990 to 1999.
2020s – Refers to the decade from 2020 to 2029.

Examples (UK & US):

In the 1980s, British music saw a major shift. (UK)
The 2000s were marked by technological advancements in the US. (US)

Key point: Do not add an apostrophe after the year when making it plural. The apostrophe here is unnecessary and incorrect.

2. Omission of Numbers (Apostrophe Before the Year)

Sometimes, you may want to shorten a year by omitting the first two digits. In this case, you place an apostrophe before the numbers you’re keeping:

‘90s – Short for 1990s
‘20s – Short for 2020s

Examples (UK & US):

Fashion in the ‘80s was bold and experimental. (UK & US)
Many films of the ‘90s are considered classics today. (US & UK)

Key point: Apostrophes are used here to indicate omitted digits, not to form a plural.

3. Possessive Form of a Year (Apostrophe + s)

If you want to show possession, an apostrophe comes after the year, followed by s:

The year’s biggest hits were unforgettable. ✅
2010’s top-selling book won several awards. ✅ (Note: Some style guides prefer avoiding apostrophe here; see below.)

UK vs US Usage:

UK English: Often prefers avoiding apostrophes for possessive years: 2010s biggest hits
US English: Accepts 2010’s biggest hits, though modern style guides still recommend avoiding the apostrophe unless indicating possession rather than plural.

Meaning of the Incorrect Form

The most common mistake is using an apostrophe after a plural year:

Incorrect: 1990’s, 2000’s, 2020’s (when referring to the decade)
Why it’s wrong: Apostrophes are not needed for plurals. Adding one suggests possession, which is not intended when simply talking about decades.

Another common error is inconsistent use of apostrophes when shortening years:

Incorrect: 90’s (instead of ‘90s)
This suggests a possessive or is simply grammatically wrong.

Tip: Always ask yourself, “Am I showing possession, shortening numbers, or making a plural?” This determines the correct apostrophe placement.
