How to avoid overlapping of labels in timeline plot

Question

Hey everyone, i use the plot example from https://matplotlib.org/gallery/lines_bars_and_markers/timeline.html Code is similar from the example there. Just some different values for the list names and dates.

Now i have got the problem, as shown in the picture below that some of the labels overlap. How can I avoid that? It is not the only plot of that kind i will make so it would be great to find a way that it works for any data input.

I already adjusted the space between the x-axis elements but I do not know how to fix that problem with the labels.

Found the solution thanks to the reply of @ImportanceOfBeingErnest. My 2 input lists where not sorted by date.
