Heat oven to 350° F. Lightly coat a 5-by-9-inch loaf pan with vegetable cooking spray.
Combine the flour, cornmeal, sugar, baking powder, baking soda, cinnamon, and salt in a large bowl. Stir in the dates, then the pumpkin, milk, oil, and eggs until well blended. Pour into pan.
Bake 50 minutes or until a toothpick inserted in the center of the loaf comes out clean. Turn onto a wire rack.
