If you do "datecalc -j yyyy mm dd" , datecalc will try to compute the modified julian day number of the date. This will fail if the date is not valid. You can simply test the return code:
Here I sent stderr to /dev/null. But datecalc will write a specific error message to stderr if it detects an invalid date. You may want to just send the error on to the user.
Or you can can look at datecalc to see how to test the validity of a date. But it takes some code to this, mostly due to the complex rules involving leap year.
I have one script.for that the inputs are fromdate(dd/mon/yyyy) and todate(dd/mon/yyyy).

dp
DP(8) [nmh-1.5] DP(8)NAME
dp - parse dates 822-style
SYNOPSIS
/usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...
DESCRIPTION
Dp is a program that parses dates according to the ARPA Internet standard. It also understands many non-standard formats, such as those
produced by TOPS-20 sites and some UNIX sites using ctime(3). It is useful for seeing how nmh will interpret a date.
The dp program treats each argument as a single date, and prints the date out in the official 822-format. Hence, it is usually best to
enclose each argument in quotes for the shell.
To override the output format used by dp, the -format string or -format file switches are used. This permits individual fields of the
address to be extracted with ease. The string is simply a format string and the file is simply a format file. See mh-format(5) for the
details.
Here is the default format string used by dp:
%<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>
which says that if an error was detected, print the error, a `:', and the date in error. Otherwise, output the 822-proper format of the
date.

DEFAULTS
`-format' default as described above
`-width' default to the width of the terminal
CONTEXT
None
BUGS
The argument to the -format switch must be interpreted as a single token by the shell that invokes dp. Therefore, one must usually place
the argument to this switch inside quotes.
