[LeHaven]

Methods to determine the production date of 2020 automotive glass: 1. Look for the trademark in the corner of the car glass, which consists of several dots and a number. The number represents the production year of the glass. If the dots are on the left, it indicates the first half of the year, while dots on the right indicate the second half; 2. The date code on the glass may only have a single digit, representing the last digit of the year; 3. The month can be determined by the black dots before or after the number. Dots before the number indicate the first half of the year, and the specific month can be calculated by subtracting the number of dots from 7. If the dots are after the number, it indicates the second half of the year, and the specific month can be calculated by subtracting the number of dots from 13.
