Actually, I said "From day one of the IBM PC in 1983, the main programming language was C.". I'm sorry you fell on your head and you can't comprehend the written word. From the very first post, I have been talking about 1983.If only that is what you had said. Since you can't be bothered to follow links or look back, I'll quote what you said (for a third time):
Day one of anything in 1983 is January 1st, 1983 if you want to be specific.
I can see why you're having such trouble parsing dates, you don't understand how they work at all!! Add another item to the ever growing list of stuff Harsh doesn't understand.
