come for several days - come for September 5-8

[kvvic]

Another question about prepositions of time.
I know that 'for' is used to say how long something lasts, e.g.:

Mr. X came here for several days.

I feel that it won't sound natural if I express the period after 'for' in dates. Am I right?

Mr. X came here for September 5-8.

If it's true, could you please suggest me a better way to express this idea, to indicate the dates?

If there is something unclear about my question, please let me know and I'll try to put it in another way.

There is nothing unclear about it - it was just tucked away in the 'Editing & Writng' sub-forum, where some of us rarely come. A question such as yours will usually be answered quite quickly in the 'Ask a Teacher' sub-forum.
You are right; "Mr. X came here for September 5-8" is not particularly natural, though you may here it from some speakers. The simplest way to say this is, "Mr. X stayed here from 5th to 8th September.

It also sounds OK to me without a preposition, though I wouldn't use this in formal language:
He came here September 5-8.

Thanks for your help, fivejedjon and Tdol!
