Milk's roughly 5-7 day fridge window after opening is one of the more universally known dairy timelines, but it's worth pairing that number with real spoilage signs rather than treating the date alone as a hard cutoff — a sour smell, a curdled texture, and yellowing are the clear signals that milk has genuinely turned, regardless of what the printed date says.
Freezing milk (up to 3 months) is a real option, though this site is direct about the trade-off: frozen and thawed milk separates and its texture never fully returns to normal, which is why frozen milk is far better suited to cooking or baking, where texture matters less, than to drinking straight from a glass.
Milk's fat content doesn't meaningfully change how long it lasts — whole, 2%, and skim milk all follow a similar spoilage timeline once opened, since the bacteria responsible for milk going sour act on its proteins and sugars, not primarily its fat content.
Storing milk on a middle or lower interior shelf, rather than the door, keeps it at a more stable, colder temperature — the door is typically the warmest part of the fridge from frequent opening, which can shorten milk's usable life.
A sour smell is milk's clearest and most reliable spoilage sign; visual changes like slight yellowing can appear before the smell does, so trusting the nose over the eyes is generally the safer approach.
Giving the carton a gentle sniff before pouring is a quick, reliable habit, since milk's spoilage is almost always detectable by smell before it's visible.
A carton nearing the end of its window can still be perfectly fine for baking or cooking even if the flavor has started to taste slightly less fresh for drinking.

Frequently asked questions
How can I tell if milk has gone bad without tasting it?
Smell and look first — a sour, off smell and any curdling or yellowing are reliable signs, and trusting your nose over a sip is generally the safer approach when milk seems questionable.
Does milk last longer if I keep it in the coldest part of the fridge?
Yes, meaningfully — storing milk toward the back of the fridge (colder and more temperature-stable than the door) rather than in the door shelf helps it stay closer to its full stated shelf life.
Is it safe to drink milk a day or two past its printed date?
Often yes, if it's been stored consistently cold and shows none of the real spoilage signs — the printed date is a quality guide, not a hard safety cutoff, though this site's guidance always favors caution when genuinely unsure.
Can I refreeze milk that's already been frozen and thawed once?
It's not recommended — refreezing previously thawed milk further degrades its texture and increases food-safety risk from the temperature cycling, so it's best used up once thawed rather than refrozen.
Does non-fat or skim milk spoil faster than whole milk?
Not meaningfully — the bacteria responsible for milk turning act on its proteins and sugars rather than its fat content, so skim, 2%, and whole milk all decline on roughly the same timeline after opening.
