"Title 21 → Chapter I → Subchapter H → Part 801 → Subpart A → §801.18

Title 21: Food and Drugs
PART 801—LABELING
Subpart A—General Labeling Provisions
§801.18   Format of dates provided on a medical device label.

...

(a) In general. Whenever the label of a medical device includes a printed
expiration date, date of manufacture, or any other date intended to be brought
to the attention of the user of the device, the date must be presented in the
following format: The year, using four digits; followed by the month, using two
digits; followed by the day, using two digits; each separated by hyphens. For
example, January 2, 2014, must be presented as 2014-01-02.
