=SUMPRODUCT((TEXT(A1:A9,"mmm")="Jan")*(B1:B9="x"))

This is probably basic stuff.

I presently use COUNTIF to count the number of instances
of the letter
"x" or "o" in a column:
=COUNTIF(B:B,"x")

I need to find totals of one condition in a column when
another column
has another condition.

In the following data range, for example, I might need
to find the
number of times "x" appears in column B during a
particular month, like
February, or during a certain time of day.

A B C
January 4 x morning
January 4 o afternoon
January 12 o morning
January 15 o morning
January 15 x afternoon
February 2 x morning
February 2 x morning
Ferbrary 4 o morning
February 10 x morning

I might also like to count, for example, the number of
times "x"
apppears in the morning in February.

Please write out examples. My date format is MM-DD-YY.
