Milk is usually best used within about a week after opening, but the date and fridge temperature matter.
How it smells and how it was stored are also important.

Keep milk refrigerated and return it to the fridge quickly after pouring. Leaving it out on the counter shortens its life.
Store milk tightly closed and avoid drinking straight from the carton. That can introduce bacteria and affect freshness.
Do not use milk that smells sour, looks curdled, tastes off, or has been left out too long. If it is close to spoiling, freezing or cooking with it may be an option only if it still seems normal.
Opened milk needs cold, clean handling. The date helps, but smell, texture, and storage history decide the final call.
