I could not get some of the sophisticated REGEX stuff to work (calculates leap 
year stuff). This is what I ended up using: 

RULE: datefromVALID 
CRIT: REGEX 
ARGS: ^((0?[1-9])|(1[0-2]))/((0?[1-9])|([12][0-9])|(3[01]))/[0-9]{2,4}$ 
FFLD: datefrom 
MESG: - starting date, must be mm/dd/yyyy format. 
### 

it only allows 1-12 for the mm field and 1-31 for the dd field. Also, it 
allows yy or yyyy variations.

> CRIT: REGEX 
> ARGS: ^[0-9]{1,2}/[0-9]{1,2}/[0-9]{4}$
