Based on my kids, they will last quite a while.
More than a month. They will separate and you will see solids form on the bottom when they are bad.
Also, NO expiration dates on bottled juices. I have 5 in the fridge now and not one ex date. OJ, Grapefruit and others found in cartons htat are made from fresh or concentrate DO have ex dates. Apple Cider is included with this group.
