How to Determine a Car's Manufacturing Year from Its Windows?

[Betty]

To determine a car's manufacturing year from its windows, follow these methods: 1. Look for the code at the bottom left or right corner of the window glass; 2. The number represents the year, and the dots represent the month. Dots before the number indicate the first half of the year, and the month can be calculated by subtracting the number of dots from 7. Dots after the number indicate the second half of the year, and the month can be calculated by subtracting the number of dots from 13. Classification and functions of car glass: 1. Laminated glass: This type of glass has a transparent adhesive plastic film sandwiched between two or three layers of glass, enhancing its resistance to breakage; 2. Tempered glass: This is made by quenching ordinary glass to create internal stress. When impacted, it shatters into small, blunt-edged pieces, reducing the risk of injury to passengers.
