Little help please

Age of this furnace? Is it April, 2004?

American Standard
Model #: ADD120R9V5C5
Serial #: N404WG92G

American Standard uses the same code as Trane. YWWD

In this case N = 1998
40th week (early October)
and I’m guessing 4 = Thursday

You can find the year codes here… http://www.trane.com/Residential/TraneOwners/OwnersFAQ.aspx#TO5
