According to the DIN ISO 8601 a German date needs to be formated without a linebreak between in it.
So LaTeX have to break before or after the date.
Instead sometimes a date exceeds the linewidth.

See the MWE:

```
\documentclass{article}
\usepackage{lipsum}
\usepackage[ngerman]{isodate}
\numdate
\overfullrule=3pt

\begin{document}
\lipsum[2]
abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefgh \printdate{16.09.2014} abcdefg hijklmnop
\end{document}

```

How to handle this issue, that the date isn't exceeding?
