I am using the following formula (and it works!) to calculate the number of
dates that equal january, feb, and so on.

=SUMPRODUCT(--(MONTH('Raw Data'!H$4:H$18)=1))

Within the raw data, I also have the word "unscheduled" where a date should
belong. I am now getting errors with my formula. How do I add - if the cell
doesn't = unscheduled, then sum product?

Thanks!!

One way:

=SUMPRODUCT(--(TEXT('Raw Data'!H4:H18,"mmm")="Jan"))

Try this

=SUM(IF(ISNUMBER(H$4:H$18),IF(MONTH(H$4:H$18),1)))

as an array formula, commit with Ctrl-Shift-Enter rather than just Enter

One way:

=SUM(IF(ISNUMBER('Raw Data'!H$4:H$18),--(MONTH('Raw Data'!H$4:H$18)=1)))

This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)
