I had a friend who used to do chirography. I think my Mum liked him better than me because he actually had talent.

Of course this immediately sent me searching for the difference between chirography and calligraphy.Mirriam-Webster did not help by listing calligraphy as a synonym for chirography.

Further searching indicates that chirography is what could be call good penmanship or handwriting in the usual sense of using a pen or a pencil or I suppose a finger in the sand at the beach. Calligraphy indicates that the the handwriting has been done at an artistic level.  

My handwriting would never be describes as "artistic" and probably doesn't even come up to the standard of chirography. I welcomed the invention of personal computers because they made typing so much easier and what I wrote so much more legible.

To whom it may concern, I never said my preferred site was perfect(M-B), enough said.

I found this on another site, that I think better(?) answered your question:

Calligraphy

• Definition: Calligraphy is the art of beautiful handwriting. It involves the design and execution of lettering that is expressive, harmonious, and skillful.
• Focus: Emphasizes aesthetic quality and artistic expression. Calligraphy often uses specialized tools like brushes, pens, or quills.
• Applications: Commonly used in formal invitations, certificates, and artwork.

Chirography

• Definition: Chirography refers to the practice of handwriting or the study of handwriting. It can be seen as a broader term that encompasses all forms of handwriting.
• Focus: Primarily concerned with the technique and style of writing by hand, without the artistic emphasis found in calligraphy.
• Applications: Often related to practical handwriting skills, education, and personal style.

A note for the two other comments given so far;

The fact that you are here, that we know your name, should be a tell to you of your talent.

You are in luck, they don't teach handwriting skills in school anymore. As long as you can type, you can change the type of script, font, size and color that you use. Code books, no longer required.

Just the facts:

While I was making my last comment I came across this interesting/fascinating read.

Diplomatics - Formats, Scripts, Seals | Britannica

An extract from the above:

From Roman times the two most important methods of validating documents were by appending the signature or the seal of the sender or promulgator. The practice of using seals for this purpose (and not merely to close a document) was carried over from imperial usage and, by the 8th century, was current among the Lombards and other Germanic tribes in western Europe. Until about the 8th century, the signature of the Merovingian ruler or his delegate was also required for the validation of public documents, but thereafter the seal alone, together with the recognition by a high chancery official, was held sufficient, the king’s signature dwindling into a monogram or mere stroke (the “stroke of execution”). This change was probably accelerated because many medieval kings could not write. Thus, in England, King John sealed, and did not sign, the Magna Carta.
