Few issues with Tikz Calendar

I have been trying to implement my own agenda since those from the store never really satisfied me. I have now more or less what I wanted to get. I still have minor issues I can’t workaround. So if someone has any tips :

1. I display only Monday, Thursday and Friday on the calendar (that appears on each weekly page in the upper right corner). So far the only working solution I have found is a negative "xshift" on days I don’t want to display, otherwise, a blank space remains. But for some reason, it works fine except on weeks where the monday beglon to another month than the Thursday and Friday. In that case, a larger blank space is added for some reason, and I don’t know why.

2. The calendar displayed on each page do not show the last vertical line whilst it is written in the tabular definition I use for the daytext…

3. The names of the days and the month refuse to translate to french, and I cant figure out why, I paid attention to the usepackage position but still, it does not work.

4. A great icing would be to display a different calendar depending on the week (the value of n in my code, some calendar if n is odd, another if n is even). I don’t know how to do that.

A regular week with issues 2 and 3

The ugly week with issue 1 (and 2 and 3 for that matters)

Thanks a lot for any input!
Cheers!
