Why These Forms Are Confusing
The confusion mainly comes from apostrophes.
Many people mistakenly add apostrophes to plural words, even when no ownership is involved.

Because both forms sound identical when spoken, writers often rely on guesswork instead of grammar rules.
Understanding Plural and Possessive Forms
Plural Form: Thursdays
Used when discussing:
- Weekly routines
- Multiple weeks
- Recurring events
Examples:

No apostrophe is needed because the word is simply plural.
Possessive Form: Thursday’s
Used when something belongs to or relates to Thursday.
Examples:
- Thursday’s deadline is approaching.

The apostrophe shows association or ownership.
What About “Thursdays’”?

Thursdays’
This means:
Something belonging to multiple Thursdays.
Although less common, it can appear in specific contexts.
Examples:

Quick comparison:
