On average, an unopened pack of biscuits can last for around 6-9 months after the expiration date, while an opened pack can last for around 2-3 months. However, this can vary depending on factors like temperature, humidity, and air exposure. If you store your biscuits in an airtight container in a cool, dry place, they'll last longer than if you leave them out on the counter.
But, let's get real - biscuits aren't exactly the most perishable food item out there. They're basically just a mixture of flour, sugar, and fat, which makes them pretty hardy. In fact, some people claim that biscuits can last for up to a year or more after the expiration date, as long as they're stored properly. That's a long time for a snack to still be good to eat!
