I need to create a timeline in latex. This is what I have right now

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{chronosys}

\begin{document}


\startchronology
[startyear=0,stopyear=44,height=7ex,width=\hsize]
\chronoevent{0}{Jan 13 Quiz 1}
\chronoevent{8}{Jan 20 Quiz 2}
\chronoevent{36}{Feb 17 Quiz 6}
\chronoevent{36}{Intervention}
\stopchronology

\end{document}

I would like to have the days on top of the timeline, and the quizzes, and intervention, in the bottom.


I was able to create something close to what I want:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{snakes}
\usepackage{fullpage}

\begin{document}



\begin{figure}
\caption{Time Line}
\centering
\resizebox{\linewidth}{!}{% Resize table to fit within

\begin{tikzpicture}[]
%draw horizontal line   
\draw (0,0) -- (41/1.7,0);
%draw vertical lines
\foreach \x in {0/1.7, 8/1.7, 15/1.7, 22/1.7, 29/1.7, 36/1.7, 41/1.7}
   \draw (\x cm,3pt) -- (\x cm,-3pt);

%draw nodes
\draw (0,0) node[below=3pt] { Quiz 1 } node[above=3pt] { Jan 13 2014  };
\draw (8/1.7,0) node[below=3pt] { Quiz 2 } node[above=3pt] { Jan 20 2014  };
\draw (15/1.7,0) node[below=3pt] { Quiz 3 } node[above=3pt] { Jan 27 2014  };
\draw (22/1.7,0) node[below=3pt] { Quiz 4 } node[above=3pt] { Feb 3 2014  };
\draw (29/1.7,0) node[below=3pt] { Quiz 5 } node[above=3pt] { Feb 10 2014  };
\draw (36/1.7,0) node[below=3pt] { Quiz 6 \& Intervention} node[above=3pt] { Feb 17 2014  };
\draw (41/1.7,0) node[below=3pt] { Course ends} node[above=3pt] { Feb 22 2014  };
\end{tikzpicture}
}
\label{fig:time_line}
\end{figure}
\end{document}

But the "draw vertical lines" is not doing what I expected.

%draw vertical lines
\foreach \x in {0/1.7, 8/1.7, 15/1.7, 22/1.7, 29/1.7, 36/1.7, 41/1.7}
   \draw (\x cm,3pt) -- (\x cm,-3pt);

Any idea why?

You have some mistakes in your \foreach. Use

%draw vertical lines
\foreach \x in {0, 8, 15, 22, 29, 36, 41}{
   \draw (\x/1.7,3pt) -- (\x/1.7,-3pt);
}

I have used /1.7 in the coordinate instead of the list where / will be confused foe the next variable.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{snakes}
\usepackage{fullpage}

\begin{document}



\begin{figure}
\caption{Time Line}
\centering
\resizebox{\linewidth}{!}{% Resize table to fit within

\begin{tikzpicture}[]
%draw horizontal line
\draw (0,0) -- (41/1.7,0);
%draw vertical lines
\foreach \x in {0, 8, 15, 22, 29, 36, 41}{
   \draw (\x/1.7,3pt) -- (\x/1.7,-3pt);
}
%draw nodes
\draw (0,0) node[below=3pt] { Quiz 1 } node[above=3pt] { Jan 13 2014  };
\draw (8/1.7,0) node[below=3pt] { Quiz 2 } node[above=3pt] { Jan 20 2014  };
\draw (15/1.7,0) node[below=3pt] { Quiz 3 } node[above=3pt] { Jan 27 2014  };
\draw (22/1.7,0) node[below=3pt] { Quiz 4 } node[above=3pt] { Feb 3 2014  };
\draw (29/1.7,0) node[below=3pt] { Quiz 5 } node[above=3pt] { Feb 10 2014  };
\draw (36/1.7,0) node[below=3pt] { Quiz 6 \& Intervention} node[above=3pt] { Feb 17 2014  };
\draw (41/1.7,0) node[below=3pt] { Course ends} node[above=3pt] { Feb 22 2014  };
\end{tikzpicture}
}
\label{fig:time_line}
\end{figure}

Current version of chronos is available at:
https://tex.stackexchange.com/a/342699/ (2016-12-06)

This is a shameless imitation of Harish Kumar's timeline, reproduced using a version of chronos specially bug-fixed and modified for the occasion.

Essentially, with the code below for chronos, we can write

\begin{tikzpicture}
  [
    chronos={%
      start date=2014-01-13,
      end date=2014-02-22,
      date format={b d Y},
      timeline width=150mm,
      event dates split,
      event distance=-3pt,
      timeline margin=1pt,
    }
  ]
  \chronosevent {2014-01-13}{Quiz 1}
  \chronosevent {2014-01-20}{Quiz 2}
  \chronosevent {2014-01-27}{Quiz 3}
  \chronosevent {2014-02-03}{Quiz 4}
  \chronosevent {2014-02-10}{Quiz 5}
  \chronosevent {2014-02-17}{Quiz 6\\\& Intervention}
  \chronosevent {2014-02-22}{Course ends}
\end{tikzpicture}

to produce

chronos split events

This version of the code adds the possibility of splitting events across the line (date above and text below or vice-versa) and fixes a bug which caused a never-ending loop if the start and end date were in the same year.

Complete code (2016-08-22):
