You can tell that walnuts are getting old if they are rubbery or wrinkled. They have gone rancid if they have a strange smell similar to paint thinner. If the walnuts look good, smell them. If they still have that fantastic nutty smell, they're still fresh.
However, if they smell a little sour, like paint thinner, it's best to avoid eating it. The best way to know if the nut is bad is to look at the shell. If it has been damaged, the shell will look wrinkled and shrunk. In other words, a stale nut will have an unhealthy shell.
If the shell looks good, open a few to see what's inside. Since you plan to eat only a small amount every day, the package of shelled walnuts you bought will last quite a while. So, if you shake your shelled nut and hear the walnut moving inside it, it's time to throw it away. Shelled walnuts are kept for at least half a year at room temperature and more than a year in the refrigerator.
It is important to ensure that the package or container is sealed, as this will prevent oxygen from pooling with the nut fats and rancifying them, and will also block moisture and odors from the environment. For shelled walnuts, refrigeration is what I recommend, especially if you need them to last longer than a couple of months. In other words, when it comes to in-shell walnuts, open them before assuming they're in poor condition because they've been stored for too long. To ensure the best flavor, it is recommended to store shelled walnuts whole and not chopped or ground.

As I mentioned in the spoilage section, walnuts are prone to going rancid, thanks to their nutritional profile. As a rule, it is best to wait until you are ready to use the nuts before removing the shell, as this significantly improves their quality.
A healthy shelled nut weighs when you pick it up, and when you shake it, you can't hear the movement of the grain inside the nut. In other words, instead of relying on the printed date, you should do a quality check on your nuts and go from there. So, if you don't plan to consume your shelled walnuts quickly, it's best to store them in the fridge.
