Wall calendar with monthly background and moon days (if possible)

Question

I have been working based on this answer but I can't get the background to change for each month. The moon feature from this answer is also not working for this tikz. There are also some minor changes, so in summary:

• A PNG tiled background should be different for each month.
• Whole month border.
• Include moon phases before the day number (if possible).
• No vertical lines at the days of the week.
• Horizontal lines for hand writing.
• Rounded corner border around month - year.

Also, how do I change language?

Answer 1

How it works

• It's much easier (for me) to use TikZ to create the whole page instead of using geometry and such things.

• A lot of dimensions are controlled via key values in the /cal namespace (see \calset), this includes

  • the page dimensions,
  • the borders (border top is the space between weekdays and the header)
  • the header dimensions (current you need to make sure it is wide enough to fit the longest head).

• The background is done via layers at the end of the picture, a background for each month can be set by set background = {<month number>}{<TikZ styles>}.

  You can see two examples for 6 and 7.

• Translations are provided by the babel package and implemented via the translator package (this is a feature of the calendar utility) which needs to be loaded before TikZ. (This is why I'm using multi=tikzpicture instead of tikz as a class option since otherwise standalone would load tikz before we have a change to load translator before.)

• The language is given as a class option. Since you didn't specify the language I'm using ngerman for this example.

• Since you don't want a background for the days of the week from the previous or next month, I'm using my ext.calendar-plus library to be able to use the conditionals and, week of month and calendar week of month (and their ' variants) to add another day in the appropriate places.

  This is taken from Full weeks in Tikz Calendar

• No vertical lines between the weekdays is done by removing the draw option in every weekday and just draw a rectangle around them at the end.

Todo

• Lines to write on.

• What to do with months that have less than 6 weeks?

  Currently the height of the day boxes doesn't change like in TikZ / calendar: Set the height of a monthly calendar

  At the bottom of the page remains empty space which doesn't even have an extra area to write on.

• Moon stuff. (It will be easier to provide the dates instead of calculating them, especially when we're thinking about time zones.)
