If you knew when and where you were going to die, would your life be better?

I guess so, since I would be like, I'd die that time so I would enjoy this time, if somehow my life is only until next year then I would now marry my fiancée and not wait for later, do a bunch of things that I want to do before I die, make peace with people that means a lot to me and make my life happier and meaningful by volunteering instead of working my a$$ off for money that I might not be able to use anyway

I'd rather not knowing it. Firstly, if we know when we will die, of course when it is still far ahead we would be really happy as we know that we are immortal. But when the time is near (around a few months), than that must be the problem. You will start worrying about yourself, your family etc.
