Treat the dates here as a convenience, not a safety guarantee. Here is where they stop.

The product date wins

This tool adds a shelf life that you enter to a start date. It has no knowledge of how long a specific food, medicine or product really lasts. The printed date and the maker's instructions always take precedence over anything calculated here.

Storage changes everything

How long something keeps depends heavily on how it is stored, temperature, light, humidity and whether it has been opened. A calculated date assumes ideal conditions, so real life may be shorter.

Not food-safety or medical advice

Nothing here is food-safety, medical or pharmaceutical advice. For anything you eat, drink or take, follow the use-by date and, when in doubt, throw it out or ask a professional.

The bottom line

We do the date maths and take care, but we can't promise a result matches your actual product, and we take no responsibility for decisions made on the strength of it.
