Almond bark is a vegetable oil based candy coating. With proper storage the bark can be kept for while. This is a guide about storing almond bark.
How long does white almond bark last? I have a package from last Christmas. It still looks and smells good, but I don't want to use it if it could go bad.

If you're talking about baking usage it will be just fine :-) Even to simply eat it is still good but just might not 'look fresh'. Any type of chocolate stays good just about forever ;-)
I bought a package of almond bark last year on sale. I just used it to dip pretzels in for the holidays. No problem at all, they are delicious.
I buy loads of almond bark on sale after Christmas and freeze it. I've had some of it SEVERAL YEARS and it was fine. It does seem to lose color after a while but it still tastes and works great.
I have used 2 year old white almond bark and my husband still liked it. After 2 years it does not harden right.
