Julian code dating
There are two types of expiration date codes on products.The first type is open dating, which uses a standard time or calendar date.What I ask for was the Julian Date of the day of the year, example 10 Sep, 2001. If there is a Julian dateformat "yyddd" I would have liked to had that code.I wouldn't have spent so much time trying to figure it out.
We also have Julian date calendar specifically which has the date countdown for the year 2018.
All other dates and codes are added voluntarily by manufacturers.
Whether you’re a consumer who is interested in determining when the product that you want to buy is going to expire, or a grocer who is taking initiative to track expiration dates, learning how to read different types of expiration date codes is an important skill.
The Truncated Julian Day is a parallel grouped binary time code designed for spacecraft applications.
Introduced by NASA and Goddard in 1979, it is a four-digit day count from MJD 40000, or May 24, 1968 expressed as a binary number.Expiration dates can be hard to locate on a product and even more challenging to decipher.
