How to Check the Date on New Car Glass?

[SanTheo]

To check the date on new car glass, follow these steps: 1. Look for a code in the lower left or right corner of the window glass. The last or second-to-last row contains a number and several small black dots, which indicate the production date of the glass. 2. The number represents the production year of the glass, specifically the last digit of the year. For example, an 8 indicates 2008. 3. The small black dots denote the production month. If the dots are before the number, subtract the number of dots from 7. If the dots are after the number, subtract the number of dots from 13. The result is the production month. 4. Some glass production dates also include a few larger black dots after the date, which specify the week of the month. For example, 5 dots represent the first week, and 4 dots represent the second week.
