Why the freezer is not an option here
The USDA marks the freezer as not recommended for this item, so the answer comes from the refrigerator after opening figure: 2 days. The source fills 2 of its fields outside the freezer here, and every one of them is printed below. It is not a warning: food held at 0 °F stays safe, so a not-recommended is a verdict on what would come out of the freezer.

What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
In the refrigerator. Unopened product will last 3 - 5 days after date on bag; after opening it will last 2 days.
Can you freeze bagged greens?
The USDA does not recommend freezing bagged greens. It is not a safety warning, since food held at 0 °F stays safe, but they come back changed. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if bagged greens have gone bad
Go by the date first: bagged greens keep 2 days in the fridge once opened. Mold, slime, a sour smell or soft dark spots mean it goes out; firm produce can be saved by cutting 1 inch around a small moldy spot, soft produce cannot.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 2 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Bagged greens, leaf, spinach, lettuce, etc. is cut and ready to eat. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.
It is past the date. Now what?
Say the calculator above puts Bagged greens, leaf, spinach, lettuce, etc. past its 2 days in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
