Julian Date

[WINDSEAKER]

I am trying to figure out a Julian Date formula given by an instructor. =DATEIF(DATE(2009,12,31),DATE(2010,A6,B6),"D") with A6 and B6 equals "1" , I get "1/1/1900"??
I thought it should give me a whole number? like Fed. 2, would be 33!

Any ideas about what he is trying to do here??

Thank you

PS Im running excel 2007

try formatting the cell general instead of date
