How to Check the Manufacturing Date of New Car Glass?
1 Answers
Check the code at the bottom left or right corner of the car window glass. The format consists of numbers and dots, where the dots can be either before or after the numbers. The numbers represent the year, small dots represent the quarter (there are 4 quarters in a year), and large dots represent the corresponding month within the quarter (each quarter has 3 months). If the dots are before the numbers, it indicates the first half of the year. Subtract the number of dots from 7 to get the month in the first half. If the dots are after the numbers, it indicates the second half of the year. Subtract the number of dots from 13 to get the month in the second half.
