Cream cheese has a long fridge life when not opened. Once opened it will last about two weeks before it starts to dry up if not wrapped good enough. Just smell the cheese and you will know if it is still good to eat. If it is wrapped up good, it will and should last by the date on the package.
Cream cheese lasts for about two weeks after the package has been opened. It needs to be kept cool and in the fridge to keep for the two weeks. An unopened package of cream cheese will keep until it's expiration date if kept cool.
