Counted from the day you bought it. Figures are the USDA FSIS FoodKeeper table's, for unopened storage at room temperature; FoodKeeper counts a month as 30 days.

The table was not pulled from USDA — fsis.usda.gov answers 403 to non-browser clients from this machine — so it came from a mirror of the data.gov dataset and its vintage is unverified. Treat a single figure as indicative, not as a use-by date.

See Keeps 60 days or more for the rest of the long shelf.
