SQL Developer, INSERT dated: error - ORA-01843: not a valid month

I am running this to insert values in the table:

CREATE TABLE SERVICIOS
(
    ID INTEGER PRIMARY KEY NOT NULL,
    FECHA DATE NOT NULL,
    HORA TIMESTAMP NOT NULL,
    DISTANCIA DECIMAL (*,2) NULL,
    TIEMPO_REQUERIDO INTEGER NULL,
    DIRECCION_ORIGEN VARCHAR2(255) NULL,
    DIRECCION_DESTINO VARCHAR2(255) NULL,
    TARIFA DECIMAL (*,2) NULL,
    ESTADO VARCHAR2 (255) NULL,
    TARIFA_DINAMICA VARCHAR2(1) CHECK ((TARIFA_DINAMICA = 'V') OR (TARIFA_DINAMICA = 'F')),
    MEDIO_PAGO_ID INTEGER NOT NULL,
    CONDUCTOR_ID INTEGER NOT NULL,
    VEHICULO_ID INTEGER NOT NULL,
    CLIENTE_ID INTEGER NOT NULL,
    SERVICIO_COMPARTIDO_CLIENTE_ID INTEGER NULL
);

    insert into SERVICIOS (ID, FECHA, HORA, DISTANCIA, TIEMPO_REQUERIDO, DIRECCION_ORIGEN, DIRECCION_DESTINO, TARIFA, ESTADO, TARIFA_DINAMICA, MEDIO_PAGO_ID, CONDUCTOR_ID, VEHICULO_ID, CLIENTE_ID, SERVICIO_COMPARTIDO_CLIENTE_ID)

values (4923, '05/05/2018', '6:15 AM', 3.3, 33, '87445 Dorton Park', '589 Miller Parkway', 83502.13, 'INACTIVO', 33573.67, 15, 25, 29, 30, 90);

But I get this error:

  

Error starting at line: 2 of the command:
  insert into SERVICES (ID, DATE, TIME, DISTANCE, TIME_REQUIRED, ADDRESS_ORIGIN, ADDRESS_DESTINATION, RATE, STATE, DYNAMIC_DATE, MEDIA_PAYMENT_ID, DRIVER_ID, VEHICLE_ID, CUSTOMER_ID, SERVICE_COMPARTIDO_CLIENTE_ID)

  Error Report - ORA-01843: not a valid month

What am I failing? I have tried several things, and none has worked for me.
