Is there an easy way to sumif row entries based on dates, without having to
create an additional column for an additional formula? (i.e. month())

In other words...
I have several large ongoing database, and would like to sum sales figures
by month. The information I want to use as a criteria is the Close Date,
which is dd/mm/yy. I would normally insert an additional column adjacent to
the Close Date column, do a month(), then sumif by month # in this new
colomn. Is there an easier way to do this? I really don't want to have to
include an additional column, and for some reason, I'm not 100% on the
accuracy of this method. Am open to guidance by Those Who Know on this forum!
Muito thanks,
