EOMONTH(DATE(2004,2,29),12) results in a serial value of 38411
EOMONTH(DATE(2004,2,28),12) results in a serial value of 38411
EOMONTH(DATE(2004,1,15),-23) results in a serial value of 37315

For the 1904 date base system:

EOMONTH(DATE(2006,1,31),5) results in a serial value of 37436
EOMONTH(DATE(2004,2,29),12) results in a serial value of 36949
EOMONTH(DATE(2004,2,28),12) results in a serial value of 36949
EOMONTH(DATE(2004,1,15),-23) results in a serial value of 35853
