Just eat it. Most things are good way way past that date anyway. They purposely make that date way sooner than needed so if you get sick for any reason they can point to the silly expiration date and say, "see your milk was only good for 18 hours, and you drank it 3 whole days later, you deserve to die and it isn't our fault". Everything like that is driven by liability issues and to avoid frivolous lawsuits. In fact milk can be consumed entirely sour, it takes a good 2-3 weeks past the expiration for it to truly become "bad". We use milk that is turning to make our own yogurt in the instant pot. Just put in some milk, add a spoonful of plain greek yogurt and set it to yogurt setting and a day later we have more yogurt, which lasts a lot longer and tastes really good.
