Using Ni que + subjuntivo

Hola William,

this is a very idiomatic structure which could have different translations. We chose this one here "do you think it is August?" simply to use a sentence that conveys a surprise/abnormal situation. 

The reason why we used "estuviéramos" in the Spanish, using the nosotros form, is because we are here using another idiomatic sentence used in the nosotros form to say what date, time of year it is: "estamos a 11 de junio" "estamos en primavera", "estamos en agosto"; but we cannot translate this sentence literally into English saying something like "We are not in August." because it would sound odd in English. 

We used instead a sentence that reflects what "ni que estuviéramos en agosto" conveys. 

I hope this clarified it.
