Actually, I have discovered that Adriano's suggestion here does work:
[wpv-if f1="wpcf-start-date" f2="wpcf-end-date" evaluate="$f1 < $f2"]
[types field="end-date" style="text" format="F j, Y"][/types]
[/wpv-if]
However, I didn't realize it because my date includes a time a value. Is there a way to only evaluate the day, month and year ONLY, and ignore the time?
