I create a lot of handouts and the like for my students using LaTeX. I find that I forget to update the date field, and so I often give out handouts with the incorrect date on the top. This is a bit of a nuisance and would be easily fixed by me being slightly less lazy.
However, I save the source files in the format
[18-02-14]_Plan.tex are the handout and plan for my class tomorrow.
Does anyone know of a way that I could use the name of the file to automatically generate the corresponding date within the compiled document?
