01 -  Preheat the oven to 350°F. Line two baking sheets with parchment paper. 
 02 -  In a medium mixing bowl, whisk together the flour, ground cinnamon, baking soda, and salt. 
 03 -  In a large mixing bowl, cream the softened butter, light brown sugar, and granulated sugar using an electric mixer or whisk until the mixture is pale and fluffy. 
 04 -  Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next. Add the vanilla extract and mix until smooth. 
 05 -  Gradually add the dry ingredients to the wet mixture, mixing until just combined and no flour pockets remain. 
 06 -  Fold in the chopped dates and pecans until evenly distributed throughout the dough. 
 07 -  Drop tablespoon-sized portions of dough onto the prepared baking sheets, spacing each about 2 inches apart. 
 08 -  Bake in the preheated oven for 10 to 12 minutes, or until the edges are lightly golden while the centers remain soft. 
 09 -  Allow cookies to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
