Some additional thoughts on the topic:
"Calligraphy," as most of us presumably know, means "beautiful writing." In one sense, that is an aesthetic judgement. In another sense, it is a goal or intention. So, I would say that my mother's everyday handwriting was beautiful. She wrote relatively slowly and deliberately, but not so slowly as to hinder her productivity and not so fast as to decrease legibility. I'm sure she got good grades for "penmanship" in elementary school (almost 100 years ago now). My hunch is that her intention was to write "correctly," according to the letter forms she was taught, not "beautifully."
Then, there are those who practice writing as an art form, with the intention of creating something that will be regarded as "beautiful" and "creative," i.e., novel or unique. It may be created manually, but I have seen a good deal of contemporary "calligraphy" that is so "creative" it should not be regarded as handwriting any longer. It is reminiscent of letter forms like Picasso's Cubism paintings are somewhat reminiscent of human forms. I think this is a new phenomenon. The writing masters from the Renaissance to the 20th Century, designed and taught letter forms that were pleasing to look at but, above all, were legible and practical to use for correspondence. (The "bookhands" were another kind of writing the social value and meaning of which changed after the spread of printing with movable metal type.)
Now, my everyday handwriting these days is cursive italic. It is unusual enough to elicit comments from bank tellers, post office clerks and, before I retired from practice, pharmacists. The most common comment is something like "beautiful/nice handwriting/penmanship!" Occasionally, some one will call it "calligraphy" just because they regard certain handwriting styles as "calligraphy," without necessarily making an aesthetic judgement.
Language is wonderful.
