Whats wrong with my sql? Ora-01847 Error

[valerie-landry]

INSERT INTO TBLCASE (CASEID, OFFENSEDATE, CONVICTIONDATE, RELEASEDATE, REGISTRATIONDATE, PAIDREGESTRATION, ANNUALREGISTRATION, COMPLIANCE, NAMEID, VERIFICATIONDATE, OFFICERNAME)
VALUES (51, TO_DATE('6/19/2007', 'MM/DD/YYYY'), TO_DATE('6/19/2007', 'MM/DD/YYYY'), TO_DATE('6/19/2007', 'MM/DD/YYYY'), TO_DATE('6/19/2007', 'MM/DD/YYYY'), 0, '0', NULL, '434494734', TO_DATE('6/19/2007', 'MM/DD/YYYY'), NULL)"

I am getting an Ora-01847: day of month must between 1 and last day of month. Those dates are right.
