Thursdays vs Thursday’s: The Trick to Never Get Confused (2026)

Many learners get confused between “Thursdays” and “Thursday’s” because they look almost the same. The only visible difference is a small apostrophe, but that tiny mark changes the meaning completely.

If you are a student, ESL learner, or beginner, this can feel tricky at first. The good news is that once you understand one simple rule, the confusion disappears.

This guide will explain everything in very clear and simple English so you can use both forms correctly every time.

Quick Answer

Here is the simple difference:

• Thursdays = plural form (more than one Thursday)
• Thursday’s = possessive form (something belongs to Thursday)

Examples:

• I go to class on Thursdays.
• Thursday’s meeting was canceled.

That’s the core idea. Now let’s break it down step by step.

Simple Background Explanation

In English, we change words in two common ways:

1. Plural form → to show more than one
2. Possessive form → to show ownership or belonging

Days of the week follow these same rules.

• Adding -s makes a word plural
• Adding ’s shows possession

So:

• Thursday + s = Thursdays
• Thursday + ’s = Thursday’s

This is why they look similar but mean different things.

Clear Explanation of the Difference

What does “Thursdays” mean?

Thursdays is the plural form of Thursday. It means more than one Thursday or something that happens regularly on that day.

Use it when talking about habits, routines, or repeated events.

Examples:

• I have football practice on Thursdays.
• Shops close early on Thursdays.
• We meet every Thursdays evening.

What does “Thursday’s” mean?

Thursday’s is the possessive form. It shows that something belongs to Thursday or happens on a specific Thursday.

Examples:

• Thursday’s class was very interesting.
• I missed Thursday’s lecture.
• Do you remember Thursday’s weather?

Think of it like this:
If you can say “the class of Thursday,” then “Thursday’s class” is correct.

Common Mistakes People Make

1. Using an apostrophe for plural

❌ I go to school on Thursday’s.
✔ I go to school on Thursdays.

Many learners add an apostrophe by mistake. Remember: plural does not need an apostrophe.

2. Forgetting the apostrophe in possessive form

❌ Thursdays meeting was canceled.
✔ Thursday’s meeting was canceled.

Without the apostrophe, the meaning becomes unclear.

3. Mixing both meanings

❌ I enjoyed Thursdays lecture.
✔ I enjoyed Thursday’s lecture.

Here, you are talking about one lecture, so you need the possessive form.

4. Overthinking the rule

Some learners try to memorize too many rules. Keep it simple:

• s = many
• ’s = belongs to
