• I have read the troubleshooting section and still think this is a bug.

Describe the bug you encountered:

This, is rather unintuitive:

fd -u --changed-before=2025-11-31                                                                                                                                                     1:02:18
[fd error]: '2025-11-31' is not a valid date or duration. See 'fd --help'.

If fd fails to parse the date, it should unwrap the inner error message and actually tell the user why this is not a valid date according to fd.

Describe what you expected to happen:

The fact that it might not be a valid day on that calendar year should be presented to the user. The natural inclination is to assume it's a formatting issue.

What version of fd are you using?

#fb1486f

Which operating system / distribution are you on?

Darwin 23.6.0 arm64
