There is nothing intrinsically wrong with doing that, given that the
year can be assumed to be four-digit. But in this case, the designated
string format is FFF.
Use an ISO 8601 format, and the string comparison will work as desired.
It is foolish to use MMddyyyy within data processing, although
MM/DD/YYYY may be wanted to provide a human interface in a few
countries.
There should, however, be no need to do the expensive conversion to
string; conversion of the representation of true (non-string) numbers
would be much better.
