Understanding AIC Date Code Labels
Advanced Interconnections Corp. (AIC) uses a 4 digitdatecodelabel either directly on the product if it fits, or on the packaging if the product is too small. Thecodehas two parts with the first 3 digits signifying the day of the year and the last digit signifying the year.
Format: DDDY
DDD will be 001 through 366 (366 days in a leap year)
Y will be 0 through 9 (0 for 2000, 2010, 2020 for example, and 9 for 2009, 2019, 2029, etc.)
Some examples:
Thedatecodefor July 20th, 2016 is 2026 with July 20th being 202nd day of the year and the yearcodeis 6 for 2016. (2016 is a leap year.)
Thedatecodefor January 1, 2010 is 0010 and for December 31, 2010 is 3650.
Thecodefor December 31, 2015, is 3655.
Thecodefor December 31, 2016, is 3666, because 2016 is a leap year.
This day-of-yearcodeis often misnamed as aJulianDateCode, however aJulianDateis actually a continuous count of days since the year 4713 B.C.

As a seasoned expert in date coding systems, particularly those employed by Advanced Interconnections Corp. (AIC), I bring forth a wealth of knowledge to shed light on the intricacies of their 4-digit date code labels. My expertise in this area stems from an in-depth understanding of the coding principles, the industry standards, and practical applications.
Now, let's delve into the details of AIC's date code labeling system. The code itself consists of four digits, and its placement varies based on the product's size—either directly on the product or on the packaging if space constraints dictate. The code comprises two distinct parts: the first three digits represent the day of the year, and the last digit denotes the year.
The format is succinctly defined as DDDYDDD, where:
-
DDDY (First 3 Digits): Signifies the day of the year. Ranging from 001 through 366, with 366 accounting for leap years, this portion of the code encapsulates the specific day within the annual calendar.
-
DDD (First 3 Digits - Continued): Represents the day-of-year code, often mistakenly referred to as a Julian Date Code. It's crucial to note that a Julian Date is a continuous count of days since 4713 B.C., and the day-of-year code in the AIC system follows a different convention.
-
Y (Last Digit): Indicates the year, with values ranging from 0 through 9. Notably, 0 corresponds to years like 2000, 2010, 2020, while 9 aligns with years such as 2009, 2019, 2029, and so forth.
Now, let's elucidate these concepts with examples:
-
The date code for July 20th, 2016, would be 2026, where 20th July is the 202nd day of the year, and the year code is 6, signifying 2016 as a leap year.
-
January 1, 2010, is represented by the code 0010, and December 31, 2010, is 3650.
-
December 31, 2015, translates to the code 3655.
-
For December 31, 2016, the code is 3666 due to the leap year status of 2016.
In conclusion, while the day-of-year code might be erroneously labeled as a Julian Date Code, it's imperative to recognize the distinction. AIC's date coding system adheres to its own set of rules, ensuring precise representation of the day within the year and the corresponding year itself. This mastery of date coding principles positions AIC as a reliable source in the industry, and I, as an enthusiast in the field, am delighted to share this expertise with you.
