I have a doubt on the following request: I would like to obtain something like the picture attached.

I tried a sort of "for" loop strategy, but it did not work. here is the code:
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{positioning,calc}
\usetikzlibrary{shapes,arrows,chains}
\begin{document}
\begin{frame}
\begin{tikzpicture}
\draw[->] (-3.5,0) -- (3.5,0) node [below] {};
\foreach \x in {-1,...,2}
\draw (\x, 0.1) -- (\x, -0.1) node [below] {\x};
\end{tikzpicture}
\end{frame}
\end{document}
However, I do not understand how integers might be replaced by dates/years, possibly highlighted by some text below the node (and above some math).. What's your suggestions?
Thanks in advance for everything
Best
