I never used to worry about how long food stuff is kept in the freezer in the past, because I never really bulk bought stuff and with being in the uk full time, the food got rotated naturally.
Since being retired and travelling a great deal more, I have been a bit more conscious of it. They used to recommend a 3 month keep time. No idea why only 3 months, because I have eaten food that has been frozen for years and never had a problem.
With me being away for the past 5 months, it makes sense to eat up all of my remaining food and Start a fresh, whether I need to or not.
I will add that having a freezer full of old food when covid hit was a big bonus. LOL.
