Answer 1

Your first try does addition first and then subtraction. You cannot subtract strings anyway, so that yields NaN.

The second trry has no closing ). Apart from that, you're calling getTime on strings. You'd need to use new Date(...).getTime(). Note that you get the result in milliseconds when subtracting dates. You could format that by taking out full days/hours/etc.
