The Origin of Thursdays or Thursday’s
The word Thursday comes from Old English Þūnresdæg, meaning “Thor’s day.” It referred to the day associated with Thor, the Norse god of thunder.
The name passed through Middle English forms before developing into the modern spelling Thursday.
The plural form follows a simple English rule. Most nouns form their plural by adding -s.
So:
Thursday → Thursdays
The apostrophe in Thursday’s does not mark a plural. English uses apostrophes mainly for possession and certain contractions.
That is why these forms have different meanings:
- Thursday = one day
- Thursdays = more than one Thursday
- Thursday’s = belonging to one Thursday or “Thursday is”
- Thursdays’ = belonging to several Thursdays
The spelling difference exists because the forms perform different grammatical jobs.
British English vs American English Spelling
British and American English use the same spellings for these forms.

| Form | British English | American English | Example |

| Thursday’s | Correct | Correct | Thursday’s meeting was short. |
| Thursdays’ | Correct | Correct | The Thursdays’ events were different. |
| Thursday’s for plural | Incorrect | Incorrect | I work on Thursday’s. |
Both varieties follow the same basic rule.
