An example Zhu says is being considered is to allow a car on the road only when the final digit on its license plate corresponds with the date.

Our example will successful parse the first 3 dates but not the final one because the final date string USES a two digit year that we have not provided a pattern for.

If you can provide the 3-4 digit alpha-numeric code located on the bottom of the packaging, this will allow us to determine the date of manufacture.
