it depends...look on the expiration date. As stated, check for an expiration date, but an unopened jar (glass) of black olives should hang on for a while. If it's a metal cap on a glass jar, check for swelling of the button or the top of the cap..... if swollen, or pushed up, toss them. Better safe than sorry when it comes to eating food that you're unsure of.

In our house, about two days. Seriously, if kept refrigerated after opening they should remain fresh for several weeks to a month. If not refrigerated, about two days.
