You've seen it – probably a hundred times. That mysterious three-digit number stamped on the side of your egg carton. Perhaps you assumed it was a batch code, a price inquiry, or simply random packaging noise.
But this number? It is actually the best indicator of the freshness of the eggs and food safety – and if you ignore it, that could be the reason why your quiche left everyone with an uneasy feeling.
Let's decipher what these numbers really mean – and how to use them to avoid foodborne illnesses.
🔢 The three-digit number: It's the Julian date
This number (usually between 001 and 365 ) is the Julian date – the day of the year on which the eggs were packed .
-
001 = January 1st
-
032 = February 1st
-
120 = April 30
-
365 = December 31
So if your carton says 120, the eggs were packed on April 30th , the 120th day of the year.
🥚 Important: This is not the expiration date, but the packaging date .
