I must have been sick the day they taught Julian dates in school. I have no idea. My 696 has Spec. Ord. 6332. Can anyone tell me what the date is? Thanks, Dean
 
I believe that is going to be the 332nd day of a year ending in 6; 06, 96, 86. Roughly late November.

I not only never understood the system. I never understood the reason for it's continued existence.

It is useful for calculating interest if it accrues on a daily basis. In the case of the Spec. Ord. number on S&W boxes, I guess they use it to keep track of standard shipments of product on a given day. If the product shipped was truly a Special Order I believe Spec Ord. number will be the actual order number and not a Julian Date code.
 
Julian dates help when organizing large amounts of similar product.... I used to work with haz waste.... our barrel numbers incorporated julien date as a failsafe for ID, and primarily as an internal inventory control number...
 
How about FDN (Five Digit Number) dates? They are calculated as the count of date since a base date, kind of like the Unix epoch. If the base date is chosen carefully, the FDN date has some cool properties. The base date i used was Sunday, January 1, 1900. The count of the days since then is the FDN date. If you divide the FDN by 12, the remainder is the month (January = 0, December = 11). If divided by 7, the remainder is...guess what? That's right, the day of the week with Sunday being 0 and Saturday = 6. Most importantly, the number of days between two dates can be calculated by simple subtraction. If one is calculating compound interest, that number is important, especially if it's your money being reckoned.

The Air Force supply system used the Julian date as the date a item was ordered in the supply, it help track the item when it was back ordered.

I wouldn't slept tonight with out that information. :D:D:D

I used to get calendars with the Julian date on them. Haven't seen one in years. Thank you O Great Leader!

How else could you create a document number for a supply requisition? First four digits after the DoDAAC is the Julian date. Only saying this since I saw your Army vet status... ;)
 
The story that the Spec. Ord. number is a Julian date is a myth! If it were a Julian date the highest number possible is X366 in leap years, and X365 in others. Where many Spec. Ord. numbers are less that this, there are also many that exceed X365 (or 6). I don't know what it represents, but I do know what it doesn't!

I was under the impression that the Spec. Ord. number, or Special Order number, was the Julian date if the shipment was a standard catalog item. If it was and actual special order for something not cataloged it would bear the special order number which would not correspond to the Julian date. I'm not a myth buster, but that was my understanding.
 
Julian dates are used in many logistics related fields. We used them in aircraft maintenance, survival equipment, as well as supply. It made it easy to calculate when inspections were due or as previously mentioned, how long a part had been on order.
