Windmill Blessing Day
November 25th (tomorrow) is Windmill Blessing Day. In days of old, many millers in Holland would bless their windmills on or around this date each year.
Did you know that the millers of the windmills had a system of secret communication. By positioning the blades of the mill in specific configurations their neighbors would be told if - a child had been born, a death had occurred. During the war Denmark was invaded by Germany.

So Blessings to the windmills who helped to win their country’s freedom.
