If I will know the exact date of the end of the world here are the things that I am going to do. Since everyone and everywhere in the world is at chaos, I will suggest my family members to stay at one place and reunite as we enjoy the company of each other. I will also include my family relatives same with friends. We are going to spend quality time with each other and not worrying our jobs / dilemmas that will be left behind. I will organize a party that everyone will enjoy and won't be forgotten. I will  cherish every moment of my life especially with my loved ones.
