I. This is a special moment in my life.
II. This is the special moment in my life.
I know the I. is a right sentence. How about II.? Pls.
One can have many special moments in one's life - the birth of a child, getting married, graduating from university... so sentence I is certainly correct in most cases. But if the writer is writing in a manner that selects one of these moments and places it above all others then sentence II could be used.
