it doesn't seem like it should be all that difficult. I have a column with
several (650+) dates going back to 1975. I'd now like a table that tells me
how many entries I have per year. How would I go about doing that?

Similarly, I have category columns where a particular instance fit into that
category, I entered an "X". How would I now go about figuring out how many
of each category occured each year?

Thank you in advance. You are all lifesavers!
