My objective is to create a timeline with 5 different date (13.10.13, 01.05.14, 31.05.14, 05.06.14 and 10.06.14) with:
- a brace called "Estimation WIndow 200 days from 13.10.13 to 01.05.14
- a brace called "Event Window +/-5 days from 31.05.14 to 10.06.14
- a point on the 05.06.14 called "Event day"
the packages that I have uploades are:

usepackage{tikz}

usetikzlibrary{decorations.pathreplacing,positioning, arrows.meta}

The code that I wroted is the following:

begin{tikzpicture}

% draw horizontal line   

draw[thick, -Triangle] (0,0) -- (ImageWidth,0) node[font=scriptsize,below left=3pt and -8pt]{years};



% draw vertical lines

foreach x in {0,1,2,3,4,5,6,7}

draw (x cm,3pt) -- (x cm,-3pt);



foreach x/descr in {4/t-2,5/t-1,6/t,7/t+1}

node[font=scriptsize, text height=1.75ex,

text depth=.5ex] at (x,-.3) {$descr$};



% draw node

draw[ultra thick] (2,0) node[below=3pt,thick] {13.10.2013} node[above=3pt] {};

draw[ultra thick] (3,0) node[below=3pt,thick] {01.05.2014} node[above=3pt] {};

draw[ultra thick] (4,0) node[below=3pt,thick] {31.04.2014} node[above=3pt] {};

draw[ultra thick] (5,0) node[below=3pt,thick] {05.06.2014} node[above=3pt] {};

draw[ultra thick] (6,0) node[below=3pt, thick] {10.06.2014} node[above=3pt] {};







draw [thick ,decorate,decoration={brace,amplitude=5pt}] (2,0.7)  -- +(3,0) 

       node [black,midway,above=4pt, font=scriptsize] {Estimation Window 200 days};



draw [thick ,decorate,decoration={brace,amplitude=5pt}] (4,0.7)  -- +(6,0) 

       node [black,midway,above=4pt, font=scriptsize] {Event Window +/-5 days};



end{tikzpicture}

The result that I obtain is:

What is the problem? Can someone help me?

Think it simple. This is my proposal for this case.

documentclass[tikz]{standalone}

usetikzlibrary{decorations.pathreplacing,positioning, arrows.meta}

begin{document}

begin{tikzpicture}[x=2cm,>=latex]

draw[thick,->] (0,0) -- (6,0) node[below,font=scriptsize] {Date};

draw (1,.1)--(1,-.1) node[below] {13.10.13};

draw (2,.1)--(2,-.1) node[below] {01.05.14};

draw (3,.1)--(3,-.1) node[below] {31.05.14};

draw (4,.1)--(4,-.1) node[below] (x) {05.06.14};

draw (5,.1)--(5,-.1) node[below] {10.06.14};

draw[<->] (1,.5)--(2,.5) node[midway,above,font=scriptsize] {Estimation Window 200 days};

draw[<->] (3,.5)--(5,.5) node[midway,above,font=scriptsize] {Event Window $pm5$ days};

draw[<-] (x.south) --++ (0,-1) node[below,font=scriptsize] {Event day};

end{tikzpicture}
