What the Numbers on Your Egg Carton Really Mean — And Why Ignoring Them Could Make You Sick

✅ How to Use the Julian Date Safely

  1. Find the three-digit number on the short side of the carton (often near the USDA grade mark).
  2. Convert it to a calendar date (a Julian date converter helps).
  3. Use eggs within 3–5 weeks of that pack date.
  4. When in doubt, throw it out—especially for dishes like quiche, hollandaise, custard, or tiramisu.
