I have a chest freezer filled with freezer baskets, each basket has one kind of product: beef, lamb, fish, vegetables etc, The baskets at the top have ready meals, bacon & sausage, and dairy products, so it is very easy to keep track of everything. Food in the freezer last forever.
Supplies taken by Scott to the Antartic were found a century later and found to be fresh and palatable, so never worry how long anything has been in the freezer, it will still be safe and useable. Unless it has been inadequately wrapped and has freezer burn.
