There’s an expiration date and a group of numbers on the foil package of my condoms. What does that all mean?
We call that a “Julian date code.” This code appears as an expiration date followed 5 digits (4 numeric, 1 alpha). For example: Oct-2005 2340U In this sequence the expiration date is October 2005. Then the next three digits (234) represent the day of the year of manufacture and the fourth digit (0) represents the year of manufacture. The letter or letters represent machinery used in the condom’s manufacture. So to interpret this example, the 234th day of the year 2000. The manufacture date is based on the date the condom was dipped (produced). The expiration date is determined based on the date the condom is foiled. There can and generally is a difference in the dipped date and the foiled date.
