As for me, and I am sure many other people who enjoy eggs, there is a certain level of pleasure in breaking an egg. Whether I am preparing a fluffy omelet for breakfast, baking a cake or simply a quick fried rice for dinner, eggs are always on my menu. Occasionally, I get them from the farmer’s market, but the majority of the time, they are from the supermarket and are sealed in those typical boxes. As time passed, I realized that knowing the codes on these boxes is not a mere fascination, but rather a need. Have you ever looked at the numbers on the egg carton and wondered what they stand for? Those numbers may look like some kind of code, but they are easy to understand once you understand what they represent. So, let me get this straight, shall we? The Julian Date: Your Egg’s Birthday.

First of all, the three-digit code which seems to be a set of completely random numbers. This is called the Julian date and it indicates the actual day of the year when the eggs were packed. The Julian date is from 001 to 365. For instance, if you notice the code 001 on the carton, it implies that the eggs were graded on the 1st of Januar A code of 365 means December 31st. Pretty simple, right? I still recall the first time I encountered this. I was in my kitchen, looking at an egg carton and I felt like Sherlock Holmes solving a case. “Well, these eggs are from March 15th,” I thought to myself, feeling strangely proud of myself.

It’s like knowing the password to a private group of people who are passionate about eggs. The Packaging Plant Code: The Source of Your EggsBeside the Julian date, you may find a code that begins with the letter ‘P’ – this is the plant code and it indicates the location where eggs were processed.
