How long does Bok choy last in the fridge?
Turning the range into a date
Bok choy keeps 2 days sealed in the fridge. The window here is 3 days, short enough that the day it went in is worth writing down.

One of the largest freezer gains in the data
Freezing pays off here more than it does for 88% of the 188 foods where the USDA publishes both figures. The freezer gives 120 times what the sealed fridge gives: 3 days against 12 months. On the same shelf it sits 82 of 89, between Bananas at 3 days and Okra at 3 days.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. Within Produce it is filed under Fresh Vegetables.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 2 days to 3 days in the fridge. What decides that is the food and not the shelf the source files it on: Bok choy is raw and whole. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.
It is past the date. Now what?
Say the calculator above puts Bok choy past its 2 days to 3 days in the fridge window. Past that the calendar stops deciding and the food itself does. Mold, a slimy or sticky surface, soft or darkened spots, or a sour smell mean it goes out whatever the date says.
The FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Is that a long time?
7 items in the Produce list keep exactly as long as this item, 3 days, so they all share place 82 of 89 rather than being put in an order the data does not support. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 10% of them.
Items that behave the same way
All 4 of the 6 items nearest this item keep exactly as long as it does, 3 days, so the ranking around it is a tie rather than an order.
Products the USDA rates in the same places
This is a common shape of record: 52 of the 466 products are rated in the same places, freezer from the day of purchase and refrigerator from the day of purchase, and 7 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Scallops, Shrimp, crayfish and Squid, and the rest of that group is what the list below draws on. Of the ones shown, none keeps longer than this one does.

The rest of the Fresh Vegetables shelf
The USDA puts this product on the Fresh Vegetables shelf together with 58 others, and 55 of them keep longer outside the freezer. The shelf runs from Kimchi at 12 months down to Corn on the cob at 2 days. Nearest this product by window are Okra, Parsley and Asparagus, which is the order the list below is printed in. The order counts the longest window outside the freezer, so this item sits here at 3 days rather than at the 2 days sealed in the fridge its own answer prints.

If it has to keep longer than this
If it has to keep longer than 3 days, the Produce aisle gives 65 products that hold at least twice as long outside the freezer. The smallest step up is Kiwi fruit at 6 days against this one's 3 days; after it come Cucumbers, Grapes and Papaya. They are printed below in the order the step gets bigger, not alphabetically. The largest step the category offers is Coconut at 1 year. Freezing this one instead would reach 12 months, which the comparison above leaves out on purpose.

The record this page is built from
This page is built from a single FoodKeeper row, record 275 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 2 of the nine storage slots with a time, and the source prints its binding figure in days, so the window at the top of this page is the source's own number untouched. It is filed under Fresh Vegetables inside Produce, which is where every shelf comparison on this page comes from.
Where these numbers come from
How long does this food keep in the refrigerator, in the freezer, in the pantry? Can you freeze it, and how much of its shelf life is left once the package is open? Every answer on this page is the USDA’s own published figure, one of the 9 it keeps per food, and never an estimate of ours.
Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.
Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.
Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
