The methods the USDA actually rates for this item
The USDA rates only 2 of its nine storage methods for this item, and the pantry from the day of purchase and pantry after opening are what it rates. The other 7 slots are blank, and a blank is not a zero: it means no published figure, not that the method fails. On the same shelf it sits 7 of 23, between Lentils, dried at 1 year and Mung bean at 1 year.

Can you freeze peas?
The USDA prints no freezer time for peas. Frozen at 0 °F any food stays safe; whether they are still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if peas have gone bad
Go by the date first: peas keep 1 year in the pantry once opened. Insects, a musty or rancid smell, clumping from damp, or a swollen can mean it goes out. Any dish you cook with it follows the 2-hour rule, 1 hour above 90 °F.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 year in the pantry once opened. The USDA rating this place at all is the USDA saying Peas, dried split keeps there, so the figure rates how good it will be. 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.
It is past the date. Now what?
Say the calculator above puts Peas, dried split past its 1 year in the pantry once opened window. Past that the calendar stops deciding and the food itself does. Insects or webbing in the package, a musty or rancid smell, or clumping that says damp got in mean it goes out whatever the date 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.
