Thursdays vs Thursday’s: Which Is Correct? The Simple Difference Explained

When learning Thursdays vs Thursday’s, the choice depends on whether you mean multiple Thursdays or something associated with one Thursday today. The meaning of the sentence tells you which form to use. Thursdays refers to multiple Thursdays when something happens regularly on that weekday.

For example, “I visit the library on Thursdays.” In contrast, Thursday’s is used when something is associated with one Thursday, such as “Thursday’s meeting starts at noon.” From my experience, this simple distinction makes everyday writing easier to understand.

There is also an informal use of Thursday’s when it can shorten “Thursday is” or “Thursday has.” For example, “Thursday’s going to be busy” can mean “Thursday is going to be busy.” The apostrophe does not make the word more formal. Instead, it signals a different grammatical function and helps readers understand how the word is being used.

Quick Answer

“Thursdays” is the plural form of Thursday and means more than one Thursday. “Thursday’s” is the possessive form and means something belongs to or is associated with Thursday. For example, I visit her on Thursdays uses the plural, while Thursday’s meeting was canceled uses the possessive.

Why Do People Confuse Thursdays and Thursday’s?

The confusion happens because both words are pronounced almost the same and both contain the word Thursday.

The difference is the apostrophe:

• Thursdays = plural, meaning more than one Thursday
• Thursday’s = possessive, showing that something belongs to or is connected with Thursday

Compare these sentences:

• We meet on Thursdays. → More than one Thursday
• Thursday’s meeting is important. → The meeting belongs to or is associated with Thursday

A simple rule can help: If you are making Thursday plural, do not use an apostrophe.

When Should You Use Each?

Use “Thursdays” for More Than One Thursday

Examples:

A useful test is to replace Thursdays with every Thursday or multiple Thursdays.

I exercise every Thursday.

Both sentences make sense, so Thursdays is correct.

Use “Thursday’s” for Possession or Association

Examples:

• Thursday’s class was interesting.
• Thursday’s deadline is approaching.
• Thursday’s event starts at noon.
• Thursday’s announcement surprised everyone.

You can often think of Thursday’s as meaning “of Thursday” or “on Thursday.”

Common Mistakes

Mistake 1: Using an Apostrophe to Make a Plural

Incorrect:

I work on Thursday’s.

Correct:

I work on Thursdays.

An apostrophe is generally not used to make ordinary nouns plural.

An apostrophe is generally used to show possession rather than to form an ordinary plural. For more details, see this guide to apostrophe rules from Merriam-Webster.

Mistake 2: Removing the Apostrophe From a Possessive

Incorrect:

Thursday meeting was canceled.

Correct:

Thursday’s meeting was canceled.

The apostrophe helps show that the meeting is associated with Thursday.

Mistake 3: Confusing “Every Thursday” With Possession

Consider:

We meet on Thursdays.

This describes a repeated activity.

But:

Thursday’s meeting was canceled.

This refers to a particular meeting associated with Thursday.

Mistake 4: Writing “Thursday’s” When You Mean Several Thursdays

Incorrect:

I usually work on Thursday’s.

Correct:

I usually work on Thursdays.

If the word simply means more than one Thursday, leave out the apostrophe.

Memory Trick

Remember this simple rule:

Thursdays = many Thursdays
Thursday’s = something connected to Thursday

You can also remember:

No apostrophe = plural.
Apostrophe + s = possession or association.

For example:

• Thursdays → many Thursdays
• Thursday’s class → the class associated with Thursday

American vs British English

The distinction between Thursdays and Thursday’s is essentially the same in American and British English.

Both varieties use Thursdays as the plural form:

We have classes on Thursdays.

Both also use Thursday’s as a possessive form:

Thursday’s meeting starts at nine.

The main difference is not regional spelling. It is the grammatical function of the word.

Similar Words

Monday

• Mondays = more than one Monday
• Monday’s meeting = the meeting associated with Monday

The same grammatical principle applies throughout.

Final Verdict

Thursdays and Thursday’s are both correct, but they are used for different purposes.

Use Thursdays when you mean more than one Thursday or describe something that happens regularly on Thursday.

Use Thursday’s when you want to show that something is associated with, belongs to, or relates to Thursday.

So:

• I work on Thursdays. ✅
• Thursday’s meeting was canceled. ✅
• I work on Thursday’s. ❌

The key is simple: plural = Thursdays; possessive = Thursday’s.
