How long can heavy whipping cream sit in the refrigerator opened?

Once opened, heavy whipping cream can typically last in the refrigerator for about 5 to 7 days, provided it is stored properly in an airtight container. Always check for signs of spoilage, such as an off smell or changes in texture, before using it. If the cream has been kept sealed and refrigerated consistently, it may last slightly longer, but it's best to use it within a week for optimal freshness.
