How to Check the Manufacturing Year of Car Glass?

[RyleeRose]

You can check the manufacturing year of car glass on the glass itself: 1. Number plus dots: The dots can be either before or after the number. Dots before the number indicate the first half of the year - subtract the number of dots from 7. Dots after the number indicate the second half of the year - subtract the number of dots from 13; 2. Number plus small dots and large dots: The number represents the year, small dots represent the quarter (usually 4 dots), and large dots represent the corresponding month in that quarter (usually 3 dots); 3. First line shows number plus small dots, second line shows large dots plus small dots: The number indicates the production year, small dots on the first line represent months (1 dot for January up to 12 dots for December), while the second line represents days in that month - large dots stand for 10 days and small dots represent single days.
