nine days of holiday/holidays

[joham]

I've just come back from nine days of holiday (or holidays?).

I've just come back from a nine-day holiday. (Can we say 'a nine days holiday' or 'my nine days holiday' or 'my nine days' holiday'?)

Could I ask native speakers to help me please? Thank you in advance.

I've just come back from nine days of holiday (or holidays?). It's one holiday. "...from a nine-day holiday." is best.

I've just come back from a nine-day holiday. (Can we say 'a nine days holiday' no or 'my nine days holiday' no or 'my nine days' holiday'? no)

Could I ask native speakers to help me please? Thank you in advance.

I agree with 2006. Say:

I have just come back from a nine-day holiday.

Longman Dictionary says:

In this job you get four weeks holiday a year.

Would 'four weeks' holiday' or 'four weeks of holiday' be better than 'four weeks holiday'?

Thank you again.

Longman Dictionary says:

In this job you get four weeks holiday a year.

Would 'four weeks' holiday'
or 'four weeks of holiday' be better than 'four weeks holiday' ? ("of" can be used or omitted)

'four weeks of holidays' would also be correct because you may make 2 or more separate holidays out of those four weeks. (here I would keep "of")
