My personal habit is to try for the date (yyyy-mm-dd) and if that fails
go straight for yyyy-mm-dd-hh:mm:ss outright. None of these compromises!

As Matthew Melvin remarked, you want the -d test.
Or you can do this:
day=`date '+%Y-%m-%d'`
now=`date '+%Y-%m-%d-%H:%M:%S'`
mkdir "$day" || mkdir "$now" || exit 1
Those are short circuiting OR operators, this make the first choice or
if not then make the second or if not then abort.
Of course, you want to know which dir you ended up with, so maybe:
day=`date '+%Y-%m-%d'`
now=`date '+%Y-%m-%d-%H:%M:%S'`
{ mkdir "$day" && dir=$day; } \
|| { mkdir "$now" && dir=$now; } \
|| exit 1
cp stuff into $dir
