Certificate of Analysis Date Format

Information

Question The Certificate of Analysis has a numerical date format for the Manufactured Date and Expiration Date. What is the date format, year/month/day or year/day/month?
Answer

The Manufactured Date and Expiration/Retest Date on the C of A are reported as YYYY/MM/DD from our ERP system effective April 30, 2012. For example, the Manufactured Date for October 1, 2012 would be reported as 2012/10/01.

Prior to ERP implementation, the Release Date on the C of A was reported as MM/DD/YYYY. For example, the Release Date for October 1, 2012 would have been reported as 10/01/2012.
MM = 2-digit Month
DD = 2-digit Day
YYYY = 4-digit Year
