What the freezer time means
Freezer times from USDA FoodKeeper are about quality, not safety. Food kept frozen at 0 F (-18 C) stays safe indefinitely; what changes over the months is texture, moisture and flavour. Wrap hard boiled eggs tightly, press out air, and label the pack with the date so the guideline above is easy to track.
Thaw in the fridge, not on the counter. Anything that thawed in the fridge can be refrozen, with some further loss of quality; anything left at room temperature for more than 2 hours should not go back in.
Storage habits that make the difference
Keep dairy and eggs in the coldest part of the fridge, not the door, at 40 F (4 C) or below. Store eggs in their original carton to protect them and track the date. Reseal cheese tightly in wax paper or a container, and keep milk capped between pours.
