there will be a production date on the edge of the milk, or near the milk brand! Generally, this production date is for consumers to see, and there is a secret code composed of English and numbers. This secret code is the real milk production date. So how can we identify the secret code of the enterprise and know the real production date of commercial milk? The packaging of milk is generally printed: production date: 8 5 1 HDC8 H, in which: production date: 8 5 1 (for consumers), everyone can understand it; The actual production date is April 28th, 28, and the details are as follows:

The secret code: HDC8 H, which everyone doesn't know, is actually the actual production date of milk. The code here represents:

The first English letter represents the year: it is stipulated in the industry that A1 B2 C3 D4 E5 and so on H8 ... (Sometimes the year is omitted, and only the month and day are displayed).

the second English letter stands for the month: industry regulations A1 B2 C3 D4 E5, and so on E5 ... K 11 L12.

the third English letter and number represents the date: it is stipulated in the industry to add AA1, A2, A3, A4, A5, A6, A7, A8 and A9 before the 1st to 9th day;

change 1 to BB,B1,B2,B3,B4,B5,B6,B7,B8,B9 before 1th to 19th;

change 2 into CC,C1,C2,C3,C4,C5,C6,C7,C8,C9 before 2th to 29th;

change 3 to DD,D1 before 3th to 31st.

Therefore: HDC8 stands for April 28th, 28

This means that although the milk printed on the package is the production date: 8 5 1, the actual production date of the milk is April 28th, 28, which is 12 days short.

Take another example

Production date 7 6 1 (for consumers)

Code: GEB4 means that the real production date is actually May 14th, 27

The milk products factory can produce several dates a day, for example:

Production date 8 9 19 Code: HIB1 (September 11th, 28)
