Hello

I am revising my grammar and I have a question. Does Is this sentence correct or incorrect ?
They fly to London every nine and a half week_.
I don't know why there isn't an "s" to week.
Thanks a lot for your help.

Hello!

"Every" is used before a plural noun in expressions that refer to intervals:

They fly to L. every nine and a half weeks.
I see John every two days = every other (=second) day.
