If you knew the date of time precisely you die in advance, what would you like to do best ?

I would like to get out in nature , maybe a lake or canoe down a river, walk threw the woods. Being out like that always makes me feel better and at peace.

I would like to meet with all the leaders of the world, and tell them to get their sh*t together, or when I die, I will return to haunt their every sleeping moments.

whatever my clergy person says I need to do to get a good place in heaven

That would be the absolute worst thing to know.
