It would be 2020 and I think that Harry would be potion master like Snape and he created a potion to cure Coronavirus for everyone and the whole world would be saved but Harry went in disguise for this as Dr. Jason Garrison and was able to save the world and then plot Dr. Jason's own death and the world would go back to normal as himself and Coronavirus would be gone for good. And he would sell it under the name Pots and Bells Medical Care, in Diagon Alley to wizards making medical potions for a living, and then later on he becomes the potion's teacher at Hogwarts.
