I am looking for a simple way to generate calendar pages in LaTeX, something like this: http://www.latextemplates.com/template/monthly-calendar - however without me having to think about the "correct" week-days to calendar alignments. It should be possible to automatically layout the pages correctly by specifying the date (e.g. February 2017).
Furthermore, it must be possible to edit the text in the calendar easily in LaTeX, so this not just for print out and filling in with ink. I guess the best would a two step process, one that generates the LaTeX file with entries for every day, and then one can edit the agenda of particular days. Another possibility is to have the calendar entries in some simpler text format (it should be possible to have this in git version control) and parse and insert them correctly from the latex file.
