Thanks in advance

One is correct and one isn't. Do you know which is which?

Hi canadian45,

Thanks for your response.
I think "A three-day journey" is correct.

But why is "Three day's journey" not correct?

Await your explanation

Hi,

A three day journey is, as you say, correct. 'Three day' is descriptive and 'three days' ' is possessive.

Couldn't "three days' journey" be acceptable as an estimate of distance?

"How far is it, Rodeon Romanovitch?"

"Oh, it's about three days' journey from here, Sofya."

Hi teachers,

Actually, I want to know if there's any difference between "a three-day journey" and "three day's journey"

Thanks

The possessive form is not appropriate here; the journey is not a possession of 'three days'! You need an adjective, and the correct adjective is three-day. The adjective does not take an "s" or an apostrophe but it does need a hyphen, as it is a compound adjective.

Hi Jupiter

As Alan and prezbucky have already written, the correct possessive form of three days is three days'. The possessive apostrophe must be placed after the s in a plural noun such as days.

You will be able to find plenty of errors similar to three day's if you search the internet because putting the apostrophe in the wrong place is not an unusual mistake for either native or non-native speakers of English.

The word three-day is an adjective.

Otherwise, I'd say that there is basically no difference in meaning between a three-day journey and three days' journey, however I'd say that using the adjective (three-day) would be far more typical.
