When buying eggs, many people look only at the expiration date, but there’s another important date/code on the carton that tells you when the eggs were actually packed. 🥚
The “Julian Pack Date”
Egg cartons often include a three-digit number called the Julian date. This number shows the day of the year the eggs were packed.
Examples:
- 001 = January 1
- 032 = February 1
- 365 = December 31
So if you see pack date 120, that means the eggs were packed on the 120th day of the year (around April 30).
Why This Matters
Eggs can legally be sold for up to about 30 days after packaging in many places, so the expiration or “sell-by” date may still be weeks away even if the eggs are already a bit older.
Checking the pack date helps you choose the freshest carton in the store. 🛒
How to Pick the Freshest Eggs
- Look for the three-digit Julian date on the carton.
- Choose the highest number (closest to the current day of the year).
- Make sure the carton is clean and the eggs are not cracked.
Extra Freshness Test at Home
You can also try the water test:
- Sinks and lays flat → very fresh
- Sinks but stands upright → still safe but older
- Floats → best to discard
Egg freshness matters because older eggs lose moisture and quality, though they may still be safe if stored properly in the refrigerator.
🥚 Tip: Keep eggs in their original carton in the coldest part of the fridge rather than the door to help them stay fresh longer.
