Have you ever typed “the 90’s” and then paused, wondering if that apostrophe even belongs there? Or maybe you’ve written “class of 2020’s” and thought, wait, is this even a word? 🤔
You’re not alone. The apostrophe before or after a year is one of the trickiest little punctuation puzzles in English. It looks tiny, but it trips up students, professionals, marketers, and even seasoned writers all the time.
In this guide, we’ll break down exactly when to use an apostrophe before a year, when to use one after, and when you shouldn’t use one at all. By the end, you’ll never second-guess yourself again. Let’s dive in! 🚀
Quick Answer 💡
Use an apostrophe before a year only when shortening it (like ’90s instead of 1990s). Use an apostrophe after a year (or word) only to show possession for example, “2020’s biggest trend.” Never use an apostrophe just to make a year plural, like “1990’s” meaning “the 1990s.”
Understanding the Confusion 🧩
The apostrophe has three completely different jobs when it comes to years:
- Showing that letters or numbers are missing (contraction) e.g., ’90s
- Showing possession e.g., “2024’s top movies”
- NOT showing plurals years never need an apostrophe just to become plural
The confusion happens because these three uses can look similar but mean very different things. Let’s unpack each one with examples.
1. Apostrophe Before the Year (Contractions) ⏳
When you drop the first two digits of a year (like “19” or “20”), you replace them with an apostrophe. This is called an elision a fancy word for “leaving something out.”
Examples:
- The ’90s were full of grunge music and dial-up internet. ✅
- She grew up in the ’80s, watching cartoons every Saturday. ✅
- My parents met back in the ’70s at a college dance. ✅
- We’re seeing a huge comeback of ’90s fashion trends. ✅
The Key Rule:
The apostrophe replaces the missing numbers, just like it replaces missing letters in words like “don’t” (do not) or “can’t” (cannot).
- 1990s → **’**90s (the apostrophe stands in for “19”)
- 2000s → **’**00s (less common, but still correct)
🚫 Common Mistake: Writing 90’s instead of ’90s. The apostrophe goes before the number, not after it, because it’s replacing the missing digits at the start.
2. Apostrophe After the Year (Possession) 🏆
This is where things get interesting. An apostrophe after a year (or right before an “s” at the end) shows ownership or possession just like it does with any noun.
Examples:
- 2024’s hottest tech gadget was announced today. ✅
- 2020’s biggest challenge was the global pandemic. ✅
- The article covered 1969’s moon landing in detail. ✅
- 2023’s award ceremony broke viewership records. ✅
The Key Rule:
If the year “owns” or is connected to something that follows it (a trend, event, winner, etc.), use ‘s right after the year just like you’d write “the dog’s bone” or “Sarah’s car.”
Think of it this way: 2024’s biggest trend = the biggest trend of 2024.
3. No Apostrophe for Plural Years ❌➡️✅
This is the single biggest mistake people make. When you simply want to write a year in its plural form (talking about a whole decade), you do NOT need an apostrophe at all!
Examples:
- The 1990s brought us the internet boom. ✅ (not “1990’s”)
- Fashion from the 1980s is trending again. ✅ (not “1980’s”)
- The 2000s saw major advances in smartphones. ✅ (not “2000’s”)
Why No Apostrophe?
An apostrophe before “s” usually signals possession or a missing letter not a plural. Since “1990s” isn’t showing ownership of anything, it doesn’t need one. It’s simply plural, just like “cats” or “books” don’t need apostrophes either.
Comparison Table: Apostrophe Rules for Years 📊
| Usage Type | Rule | Correct Example | Incorrect Example |
| Shortened decade (contraction) | Apostrophe replaces missing digits, goes before | the ’90s | the 90’s ❌ |
| Possessive year | Apostrophe + s shows ownership, goes after | 2024’s best film | 2024 best film ❌ |
| Plural decade (full year) | No apostrophe needed at all | the 1990s | the 1990’s ❌ |
| Full possessive decade | Apostrophe after the “s” (for plural possessive) | the 1990s’ music scene | the 1990’s music scene ❌ |
The Memory Trick 🧠✨
Here’s a simple mnemonic to lock this in forever:
“Missing? Before. Owning? After. Plural? Never.”
- Missing numbers → apostrophe goes before (’90s)
- Owning something → apostrophe goes after (2024’s trend)
- Just plural? → never use an apostrophe (1990s)
You can also picture the apostrophe as a little comma floating in the air, “catching” whatever fell out. If nothing fell out (no missing letters/numbers) and nothing is being “owned,” leave it alone! 🙅♀️
Real-Life Examples 📝
📧 In an Email:
“Hi team, let’s revisit 2023’s marketing strategy before planning for the new quarter.”
📱 On Social Media:
“Bringing back ’90s vibes with this outfit today! #throwback”
📰 In the News:
“2020’s economic downturn was one of the sharpest in decades.”
🎓 In Academic Writing:
“The 1960s marked a significant shift in civil rights legislation.”
🗣️ In Everyday Speech:
“I still love music from the ’80s it just hits different.”
British vs. American English 🇬🇧🇺🇸
Good news this rule is basically identical in both British and American English! There’s no major regional difference here. Both styles:
- Drop the apostrophe for plural decades (1990s, not 1990’s)
- Use the apostrophe before shortened decades (’90s)
- Use possessive apostrophes the same way (2024’s headlines)
The only minor stylistic difference is that some British style guides (like The Guardian) prefer minimal punctuation overall, so you’ll rarely see apostrophes misused in professionally edited British publications but the rule itself doesn’t change across the pond. 🌍
Common Mistakes to Avoid 🚫
| Mistake | Why It’s Wrong | Correction |
| “the 90’s were great” | No possession or missing letters just plural | “the ’90s were great” |
| “in the 1990’s” | Apostrophe not needed for plural year | “in the 1990s” |
| “2024 biggest hits” | Missing apostrophe for possession | “2024’s biggest hits” |
| “‘1990s” | Apostrophe placed on the full year, not needed | “1990s” or “’90s” |

FAQs (People Also Ask) ❓
1. Do you put an apostrophe before or after the year?
It depends on the purpose. Use it before the year when shortening a decade (’90s). Use it after the year when showing possession (2024’s trend). Don’t use one at all for simple plurals (1990s).
2. Is it 1990s or 1990’s?
It’s 1990s no apostrophe needed, since you’re just making the year plural, not showing possession or a contraction.
3. Is it ’90s or 90’s?
It’s ’90s. The apostrophe replaces the missing “19,” so it goes at the beginning, not before the “s.”
4. How do you punctuate a decade correctly?
Write the full year with an “s” and no apostrophe (1980s), or shorten it with an apostrophe before the numbers (’80s). Never place the apostrophe right before the final “s.”
5. What is the rule for apostrophes with dates?
Apostrophes are used with dates only to show missing digits (contraction) or possession never simply to indicate plural.
6. Can you use an apostrophe for a possessive decade like “1990s music”?
Yes if you want to show possession for a plural decade, the apostrophe goes after the “s”: 1990s’ music (meaning “the music of the 1990s”).
7. Why do people get confused about apostrophes and years?
Because apostrophes serve multiple purposes contractions, possession, and (incorrectly) plurals and years can involve all three, making it easy to mix them up.
Final Takeaway
In conclusion, knowing whether to use an apostrophe before or after a year depends on what you are trying to say. Use an apostrophe before the shortened year, such as the ’90s, because numbers have been omitted. For plural years written in full, no apostrophe is needed, such as the 1990s.
An apostrophe can also show possession, as in 2026’s events. Remember that apostrophes are not normally used simply to make years plural. Understanding these simple rules will help you write dates correctly and avoid common punctuation mistakes in emails, articles, schoolwork, and everyday writing.
