[CollinRose]

To check the date on car window glass, follow these steps: 1. Look for the code at the bottom left or right corner of the window glass; 2. The numbers represent the year, while the dots represent the month; 3. If the dots are in front of the number, it indicates the first half of the year, and the month can be calculated by subtracting the number of dots from 7; 4. If the dots are behind the number, it indicates the second half of the year, and the month can be calculated by subtracting the number of dots from 13. The classification and functions of car glass are: 1. Laminated glass: A transparent adhesive plastic film is placed between two or three layers of glass, enhancing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to create internal stress, so when it breaks upon impact, it splits into small fragments with blunt edges, reducing the risk of injury to passengers.
