Tool Introduction
The Shelf Life Calculator works out the expiration date from a production or purchase date and a stated shelf life, then tells you how many days are left. It handles days, weeks, months and years, and flags the result as fresh, expiring soon or already expired.
It’s handy for pantry stock, fridge leftovers, medication and cosmetics - anywhere a printed date is hard to read or the label has worn off. Dates are estimated on the calendar, so treat the result as a guide and always check the product itself.
