How to determine the date a Church & Dwight product was manufactured:

A lot code, typically found on the bottom of product packaging, can be used to determine the date that product was manufactured. Church & Dwight lot codes generally consist of a 6-digit code, although some will include additional information. The first and second alpha digits represent the manufacturing plant. The first numeric digit represents the year of manufacture. The next three numeric digits reflect the consecutive calendar day of manufacture as determined by the Julian calendar. Various Julian calculators can be found online to convert the date to a different format. In the example below, the date of manufacture would be July 15, 2019.
