Fortnite | started on?

I would be glad if someone could help me further and I would like to know how to find out when I started to play Fortnite because this is important for private reasons so I think it was the period of Season 2 -3 or so kp

If you want to know the exact date, just look at the Windows installations when you have it installed

And what about me ps4 players can. You also sat in the PS store?
