Se sabe con el numero grabado en la bolsa, está en calendario juliano y esa es la fecha de produccion, duran maximo 10 años desde se produccion
The Julian calendar originated with the military and is still used today because of its usefulness in date calculations. There are no letters in this calendar, so simple mathematics can be used (don’t worry, we won’t make you do any math).
On an MRE, the Julian Date Code is translated using the template YDDD, where “Y” represents the last digit of the year and “DDD” represents the day of the year beginning from January 1 (ranging from 001-366). Officially, MREs are not meant to last longer than 10 years, so only the last digit of the year is used. For example, if a code read “5016” it would mean the MRE was manufactured on January 16, 2015.
Get it? You don’t have to. We created the nifty form below for you to enter your Julian Date Code and figure out how long your MRE’s shelf life will be.
