"Ameliyat ne zaman?"

Why operation is not acceptable as a translation for ameliyat ... ?

Does "ameliyat" translate only as surgery in the American sense of "operation", or also in the British sense of "doctor's office hours"?

You don't need the article necessarily in American usage, see http://ell.stackexchange.com/questions/51738/have-you-ever-had-surgery-why-does-surgery-in-this-sentence-have-no-article

in Arabic amaliyat it is closer to operation

Does surgery here mean the procedure done or the operation room ?

How can we say operation room as the place ?
