Mondays or Monday’s? (Correct Possessive Form)

When using names for days in your writing, it would help to know how to use the plural and possessive forms. You might have seen both “Mondays” and “Monday’s” in the past. This article will explain the key differences between these two spellings.

Mondays or Monday’s?

“Mondays” is the plural form of “Monday.” You should use this form when referring to multiple Mondays (i.e. “I don’t like Mondays”). “Monday’s” is the possessive form of “Monday.” You should use this when referring to an object belonging to Monday (i.e. “Monday’s news”).

Monday is a proper noun. You should use it in the singular form when referring to Monday as a single day.

If you are referring to multiple Mondays, then the plural form is required. This is the same as any noun rule in English, where you would add an “-s” to the end of the word to show multiple instances.

From there, the apostrophe comes into play to create the possessive form.

“Monday’s” is the singular possessive form. You can include “‘s” at the end of the singular “Monday” to show that one Monday owns an object.

Including a single apostrophe after the plural form, “Mondays,” allows you to show that multiple Mondays own an object.

Mondays

“Mondays” is the plural form of “Monday.” You can use this form when referring to multiple Mondays in the same sentence. They cannot own anything, though, since you are not using an apostrophe in the noun.

Here are some examples that’ll give you a better idea of how to use “Mondays” in a sentence:

• I’m not going to talk about my Mondays anymore. Nothing good ever happens during them.
• I thought you loved Mondays. You’re the only person I’ve ever met who says that.
• I’m not keen on Mondays. There’s something about them that doesn’t work for me.
• You could have told him to do it on Mondays, but you decided to give him Wednesdays instead.
• We meet most Mondays, but we haven’t been able to get together for a while. It’s a shame, really.

As you can see, “Mondays” works when referring to the plural form of “Monday.” If you are doing something weekly (and it falls every Monday), this is how you would show that.

Like most proper nouns, “Monday” can have an “s” at the end of it when you want to show the plural form. It’s like writing names like this:

• John
• Many Johns

• Suzie
• Multiple Suzies

You can add an “s” to the end of most nouns to show the plural form.

Monday’s

“Monday’s” is the singular possessive form. You should use this when one Monday owns an object in a sentence. The object almost always comes after “Monday” to make it clearer what is owned.

Check out these examples to see how to use “Monday’s” in a sentence:

• I didn’t go to Monday’s meeting. I felt like there were a few things that I should have done.
• Monday’s tribunal is going to be a rough one. Are you sure you want to go there and hear it?
• What about Monday’s documents? Are you telling me that you lost them over there?
• Monday’s vibe was off. There was something wrong with most of the guys in the office.
• I’m not sure if Monday’s schedule is correct. Is there anything you can do to fix it?

Since Monday isn’t a person, it’s not technically possible to “own” an object. However, in English, possessive nouns can own any noun that comes after them by including an apostrophe. This shows ownership without needing to own an item.

You may also find that “Monday’s” is a short form of “Monday is.” If “is” comes after “Monday,” it’s common for native speakers to contract the two words.

• I heard that Monday’s a write-off already.
• I’m not sure Monday’s the best day for this.
• Monday’s going to work well for me.

Mondays’

“Mondays'” is the rarest possessive form to come across. It is the plural possessive form, meaning that multiple Mondays own the same object or group of objects in a sentence.

You won’t often find “Mondays'” coming up in your writing. It’s uncommon to use the plural possessive form for a day of the week when the singular possessive form already works well.

Nevertheless, if you want to refer to multiple objects from the previous Mondays, you might find the plural possessive form comes in handy.

These examples will show you how to use “Mondays'” in a sentence:

• Have you got all of those Mondays’ meetings in one place? I would love to hear more about each of them.
• I’m not sure all of those Mondays’ files are correct. We need to run through them to check how they work.
• Many of those Mondays’ reports were wrong. I’m not sure if there’s anything we can do to fix them now.
• Those Mondays’ visitors are getting on my nerve. Every week they come back to ask how we’re getting on.
• What about all of those Mondays’ schedules that you decided to scrap? Do you not want to bring them back?

Tip to Remember the Difference

The trick with remembering possessive forms comes from knowing how to use the apostrophe.

To use the singular possessive form, you need to include an apostrophe and an “s” after the singular form. “Monday” becomes “Monday’s.” To use the plural possessive form, you need to include an apostrophe after the plural form. “Mondays” becomes “Mondays’.”

This tip is the easiest way to remember which form you need when you want to present a possessive.

Final Thoughts

“Monday” is a proper noun that follows typical noun rules for possessives and plurals. You may add an “s” to the end to create “Mondays” when referring to the plural. You can include an apostrophe in either “Monday’s” or “Mondays'” to show the singular or plural possessive forms.
