Hi there and sorry for the incomplete question which only a psychic could answer :-)

My problem is that I want to have my nice ganttchart or time schedule, but without including weekends. As my problem is, that if I set the dates for a project part for eg. 3 days and the next one too, than it occurs that the second one is longer as it includes the weekend. Easiest to see on AP1100 and AP1200 which should be equal in length. I would really appreciate help, thanks.

    Welcome to TeX.SE. It would be helpful if you composed a fully compilable MWE including \documentclass and the appropriate packages that sets up the problem. While solving problems can be fun, setting them up is not. Then, those trying to help can simply cut and paste your MWE and get started on solving the problem. Commented May 8, 2014 at 17:38
  • This comes late, but I liked the question. How about defining a new \newgantttimeslotformat (as in the manual) that basically reads your dates and adds a few hours, depending on the weekday. I.e. let monday be a monday [...] wednesday be translated to ~thursday [...] friday sat and sunday all become sunday. This way the 5 working days would spread evenly over those 5 days. In principle that just stretches the first 5 days of a week by factor 7/5 and the weekend by factor 0. The issue is only that you'd also have to add hours/minutes and not sure pgf does that without further fiddling

  • (And of course that is only acceptable as long as you don't show the dates in the column heading, as they would then show the wrong dates)

  • Hi and thanks for the answer. I think it might even be possible to tweek the date counting with a kind of if statement and then define days as monday to friday to finally generate a new timeslotformat, but I have no time to test it, so it'll have to wait until some day :-)

Update: Marijn has indicated how to update this to work with gant 5.0 here.

The main trick is to redefine the way that pgfgantt indexes into the chart. The package takes a date in a format specified by saying time slot format = someformat and turns it into a "Julian day number" which is " the (integer) number of days that have elapsed since the initial epoch at noon Universal Time (UT) Monday, January 1, 4713 BC in the proleptic Julian calendar.”

Then pgfgantt takes the Julian day number of a given date and turns it into "time slot," which if the compress calendar option is not present, is just (date - start day + 1) where start day is the first day of the calendar:

\newcommand\gtt@juliantotimeslot[2]{%
  \begingroup%
  \@tempcnta=#1\relax%
  \ifgtt@compresscalendar % test for `compress calendar` option
     % do something here we don't care about
  \else % set \@tempcnta = current date - start date + 1 
    \advance\@tempcnta by-\gtt@startjulian\relax% 
    \advance\@tempcnta by1\relax%
  \fi%
  #2=\@tempcnta\relax % output the result into #2
  \gtt@smugglecount#2%
  \endgroup%
}

So we need to change this indexing command to turn a Julian calendar number into the number of weekdays between the start date of the chart and the current day.

The other change we need to make is to fix the \gantttitlecalendar command. This command iterates through the days between the start day and the end day and makes a header of width (end day) - (start day) + 1. We need to fix this so that the header only counts weekdays. The main work of this command is done in the following command:

\newcommand\@@@gantttitlecalendar[3]{%
  \pgfcalendarjuliantodate{#1}{\@tempa}{\@tempb}{\@tempc}%
  \edef\gtt@calendar@startdate{\@tempa-\@tempb-\@tempc}%
  \pgfcalendarjuliantodate{#2}{\@tempa}{\@tempb}{\@tempc}%
  \edef\gtt@calendar@enddate{\@tempa-\@tempb-\@tempc}%
  \gtt@calendar@eolfalse%
  \pgfqkeys{/pgfgantt/calendar}{#3}%
  \endgroup%
}

The arguments year, month, week, day, and weekday to \ganttitlecalendar are defined as keys in /pgfgantt/calendar. We are going to define new variants of these, in /pgfgantt/calendar week days only that don't count weekdays. This is a pretty minor change, for example the days code looks like:

day/.code={%
    \ifgtt@calendar@eol\ganttnewline\fi%
    \begingroup%
    \pgfcalendar{}{\gtt@calendar@startdate}{\gtt@calendar@enddate}{%
        %%% This is the command that draws the day:
        \gantttitle{\pgfcalendarcurrentday}{1}
    }%
    \endgroup%
    \gtt@calendar@eoltrue%
}

and we need to only draw the day if the day is a weekday. So we add the code

\ifnum\pgfcalendarcurrentweekday<5\relax % 0 -- 4 are Monday -- Friday
   \gantttitle{\pgfcalendarcurrentday}{1}
\fi

The changes to the other keys are pretty similar.

One last question is what happens when you give the code dates that are on the weekend. I set it up so that start days are rounded up to Monday and end days are rounded down to Friday. In order to do this, I have to make two variants of \gtt@juliantotimeslot: \gtt@juliantotimeslot@roundup and \gtt@juliantotimeslot@rounddown and patch these into the rest of the commands in the package where \gtt@juliantotimeslot is used.

Here's the full code:
