Question: What does "D/C (YW)" on my Fluke product packaging mean?

You'll sometimes see a 4 digit number after the phrase D/C (YW) on Fluke products, especially combo kits.

This is a Date Code, an indication of when the product was packaged together. The first two digits represent the year, the second two represent the week of that year.

In the below example, a code of 2506 represents year 2025, week 06 (which was Monday, February 3rd, through Sunday, February 9th).

D/C = Date Code

(YW) = Year, Week
