Built to sit on a shelf
This item is built to sit. It keeps 1 year outside the freezer. Among the 244 foods the USDA also gives a pantry figure, it keeps longer than 51% of them. It is long enough that the date it went into storage matters more than anything you can judge by looking at it. On the same shelf it sits 7 of 23, between Rice at 2 years and Peas, dried split at 1 year.

Can you freeze dried lentils?
The USDA prints no freezer time for dried lentils. 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 dried lentils have gone bad
Go by the date first: dried lentils 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 Lentils, dried 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 Lentils, dried 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.
