How to read the production date of Lancome's Little Black Bottle

Take a Lancome Little Black Bottle as an example. The production code is 40K306, which has a total of six digits. So what do these numbers and letters mean?

1. The first two digits are the Arabic numerals "40", which means the place of origin is France.

2. The third letter "K" represents the year of production. The years are arranged in alphabetical order. For example, F represents 2009, so according to the alphabetical order, K represents 2014.

PS: But one thing we need to pay special attention to is that, because the letter I and the Arabic numeral 1 are too similar, in order to avoid confusion, the year jumps directly from H to J. Don’t forget this, otherwise there will really be a difference of one year.

3. The fourth digit represents the month of production. If it is from January to September, the Arabic numerals of the month will be used directly. If it is October to December, letters will be used to represent it, using the first letters of the English alphabet. October is represented by O, November is represented by N, and December is represented by D.

4. The last two Arabic numerals represent the production batch number, so don’t pay too much attention to them.
