How to determine week of PIII cpu?

[Spoooon]

Do you figure it out by the pack on date on the box? Or is it part of the product code?

Pack date is approximate.

Week of manufacture is in the FPO/Batch number. It's the 3rd and 4th digit.

If you have an FPO/Batch number such as L051....then it is manufactured in week 51 of year 2000.
