Source transparency
Government guidance, not invented shelf-life estimates.
The site preserves the condition-specific fields in the official FoodKeeper workbook and cross-checks common cold-storage items against FoodSafety.gov. Our calculator converts weeks, months, and years to approximate calendar dates; it does not override packaging or safety advice.
