Saturdays or Saturday’s: Which One Is Correct and Why It Matters?

Saturdays” is the correct plural form for more than one Saturday, while “Saturday’s” is only correct when showing possession.

Many people search for “saturdays or saturday’s” because apostrophes in English are confusing. You may see Open on Saturday’s on shop signs or I love Saturdays in correct writing. One small apostrophe can change the meaning of a word, and this mistake is very common in emails, social media, ads, and even professional documents.

The confusion happens because apostrophes are used for possession and contractions, but not for plural words. Since Saturday ends with “day,” people often add an apostrophe when they want to make it plural.

This leads to incorrect forms like Saturday’s when the writer actually means more than one Saturday.

This article explains saturdays or saturday’s in a clear and simple way. You will learn the quick answer, word origins, grammar rules, common mistakes, examples, and how to choose the correct form.

By the end, you will know exactly when to use Saturdays and when Saturday’s is correct.
