Lidaldi simply shows you todays week and day code used by supermarkets.
For example the code 0305 corresponds to the week starting on January 18th (week 3) and Friday (day 5) of that week so 0305 means it should be displayed until 22nd January, the fifth day of the third week.
The date is not a sell by date or best before date, but just lets you know how fresh the item is.
