Splitting ganttcharts has to be done manually, as Torbjørn T. already mentioned. Lines for milestones are also not build into pgfgantt. Weekends can be marked with
vgrid={*4{dotted},{red,dotted},dotted,{red,dotted}}
This works for gantt charts starting on Mondays. For other weekdays different patterns have to be used.
But pgfgantt can be expanded to do what you want.
The code below provides the following new options:
- vgridweek taks two parameters, which are used for the vertical lines. The second is used for the lines between Friday and Saturday and Sunday and Monday. The first is used for all other lines. It will overwrite settings done with
vgrid, even if the latter comes after this option. No default.
- weekend background sets the background color for Saturday and Sunday. If it is set to
none the weekends are not colored. Default: weekend background=none.
- milestone line is a flag. Without parameter of with
true milestone lines are drawn. With false lines are not drawn. This option can be given for a whole chart and for individual milestones. It is possible to change this setting locally for a milestone. A milestone line may be overdrawn by the line for today. Default: milestone line=false.
- milestone line style sets the style for the milestone line. It can only be set for the whole chart, not for individual Milestones. Default:
milestone line style/.style={blue,thick}.
The code below patches pgfgantt to get the new code executed at the right time. But this means, the code may not work with older or newer versions of pgfgantt (here the current version was used: 2013/06/01 v4.0).
The code:

As described in Manual/automatic line breaks and text alignment in TikZ nodes there are various ways of having line breaks in nodes. The first suggestion, with tabular, will work directly in your case I'd think. If you want to use the second or third method, you need to modify the bar inline label node style, as you're using the inline option. (Otherwise it would be bar label node.)
I think you need to change the bar height manually though, if you want the bar to be taller, so use
\ganttbar[bar height=1]{two\\lines}{1}{2} \\
\documentclass{book}
\usepackage{pgfgantt}
\begin{document}
\begin{ganttchart}[
inline,
bar inline label node/.append style={
align=center,
},
]{1}{12}
\gantttitlelist{1,...,12}{1} \\
\ganttbar[bar height=1]{two\\lines}{1}{2} \\
\end{ganttchart}

Update: Marijn has indicated how to update this to work with gant 5.0 here.
The main trick is to redefine the way that
pgfganttindexes into the chart. The package takes a date in a format specified by sayingtime slot format = someformatand 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
pgfgantttakes the Julian day number of a given date and turns it into "time slot," which if thecompress calendaroption is not present, is just (date - start day + 1) where start day is the first day of the calendar: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
\gantttitlecalendarcommand. 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:The arguments
year,month,week,day, andweekdayto\ganttitlecalendarare defined as keys in/pgfgantt/calendar. We are going to define new variants of these, in/pgfgantt/calendar week days onlythat don't count weekdays. This is a pretty minor change, for example thedayscode looks like:and we need to only draw the day if the day is a weekday. So we add the code
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@roundupand\gtt@juliantotimeslot@rounddownand patch these into the rest of the commands in the package where\gtt@juliantotimeslotis used.Here's the full code:
Here's the output (same input, first without and then with the
weekdays onlykey):
