Is it normal for a new car's glass and the car itself to be from the same month?

[DeJuliette]

It is normal for a new car's glass and the car itself to be from the same month. Here are the relevant details: 1. Car glass production date: Generally, the glass marking consists of a combination of symbols, numbers, and English letters, printed in the lower-left corner of the glass. It may appear in the form of numbers + black dots. The black dots can be either before or after the number. 2. How to read car glass markings: The method is quite simple: If the black dots are before the number, subtract the number of dots from 7; if the black dots are after the number, subtract the number of dots from 13. The result will be the production month of the glass.
