==== Best before date (expiration date) ====

The expiration date is a way to track product changes over time and to identify the most recent version. It's a data for manual usages. At this moment (2020-03), Open Food Facts apps and website don't make any usage of this field. An issue is open to [https://github.com/openfoodfacts/openfoodfacts-server/issues/76 throw off very old products in averages], it could be useful for it.

Be aware that, for the moment, this field is NOT normalized, so it probably contains dates in various formats that can be ambiguous (31/12/2019, 12/31/2019, 13 mai 2018, etc.).

It is possible to see:

* [https://world.openfoodfacts.org/state/expiration-date-completed how many products do have an expiration date] (a bit more than 10% at the beginning of 2020)
 +
* and [https://world.openfoodfacts.org/state/expiration-date-to-be-completed how many don't]

In the database and in Product Opener software, the technical name for this field is <code>expiration_date</code>.
