Check a batch code
Select a brand and enter its batch code to decode the manufacture date.
The barcode is not the batch code
The long number under the black stripes is the barcode (EAN). It only names the product — every bottle of the same item shares it, so it can't tell you a date. The batch code is a separate, short stamp (letters and numbers) printed or embossed on the base, crimp or label. That's the one to enter.
