How long is an unopened bag of potting soil good to use?

I have 2 large bags of potting soil that are a year old. I want to use the soil to pot plants that will sit out on my balcony, & possibly to re-pot some house plants. Neither of the bags has ever been opened. I was hoping to be able to use them, but not sure. Since I already bought my outdoor plants, I'd hate to throw good money after bad if this "old" soil shouldn't be used. I'm just a casual gardener & need all the help I can get! Thanks
