The Ready Store | Julian Day Calendar
MRE’s and #10 cans have a funny code on the bottom that’s called a Julian Code. It tells you when the food was packaged. It can be quite overwhelming looking over the numbers, so I have provided you a Julian Day Calendar that will help you figure out what day of the year your food storage was packaged. We do get a lot of questions like “Why don’t they just put an Expiration Date or Best Use By?” and the reason behind that is it that it depends on your storage temperature. To achieve maximum shelf life, store in an environment with a temperature of 75-60°F or lower and humidity of 10% or less. But for those who lives in a hotter climate then the shelf life will not reflect properly and so their is no way to guarantee a set shelf life of the canned product so that is why they use a Julian Date instead of the Best Used By Date.
The image displayed is a stamp on a #10 can of Saratoga Farms, and depending on what items you purchase you will have a different style of Julian Date. If you don’t know how to decipher the code it would look like some random numbers that mean nothing regarding when it was packaged. Looking off the 1st image, the first 5 digits are the Julian Code as you can see circled above. The first two numbers will represent the year and the 3 following will represent the day of the year.
So this can was packaged in 2010 on 229th day of the year, now you see the additional numbers. That references the batch and is really only applicable if there’s a recall on the product. To help you calculate the 229th day of the year I have included our Julian Day Calendar, below you will see the Days and Months of the year. By finding the number of the day you can determine exactly when the product was canned. When you see multiple numbers on the day it will show you if it is canned in a leap-year or not. (Second number is for leap-year). Leap-years will accrue every 4 years as an example: 2000, 2004, 2008, and 2012.
For Saratoga Farms Meat & Egg products they are processed in an FDA approved facility. Since the product contains meats the date on the can is different then the 1st image. You will see below letters that represents the type of can that it is (ie Diced Chicken). After the CHK will state the packaged with the Julian date 11067 decoded is March 8th 2011.
Now the 3rd option will start out each row with a letter & I do like how it will provide you with a dash between the last batch reference number and then the Julian Date. This product was packaged on 11143 or with the Julian date 11143 decoded is May 23rd 2011.

*** UPDATE for early 2011 products***
The Julian Date Stamp was not rolled over into the new year of 2011. Batches from Jan 1st to March 21st have exceeded the 365|366 date range on a Julian Date.
(Please View Example Bellow)
Date Stamp on the can above is 10418, since there are 365 days in a year you will have to “minus” 365 from what ever date is listed after the first two digits, for this example 418 and then that will give you the date of fabrication.
Using the graph above you can see that the 53rd day of the year would be February 22, 2011. You will now be able to use the graph to figure out the date of your Freeze Dried or Dehydrated #10 can was fabricated on. Another easy way to find out the date of your #10 can is to use the list below. We have provided you with a calculation time if your can has a greater date of 365.
