It is difficult to use datediff in a robust manner. For example, dates that are obviously invalid are still accepted:
$ dateutils.ddiff 2024-1x-k3 2024-01-02
2
That happens even if a particular input format is specified:
$ dateutils.ddiff --input-format="%d/%m/%Y" 2024-1x-k3 31/12/2024
366
It looks like datediff is applying the input formats only to the 2nd date specified, because this fails properly:
$ dateutils.ddiff --input-format="%d/%m/%Y" 2024-1x-k2 2024-3x-k4
ddiff: cannot make sense of `2024-3x-k4' using the given input formats
I am using the datediff 0.4.5 which comes with Ubuntu 22.04.
