Opening never extends a date: if the packet date comes sooner, go by that. Estimates for quality, not a safety ruling. What the dates mean

Potatoes keep for about 4 weeks in the cupboard, counted from when you buy them. That's SnapLarder's estimate for potatoes in general. If the packet has a date, go by the packet: it's specific to that product.

How long do potatoes last once cut?

3 days. Check the label, too: some products need to go in the fridge once opened.

Can you freeze potatoes?

Not really. Potatoes don't freeze well: the texture changes when they thaw.
