According to ancient legend, fourteen days of good weather occurred every year around December 22. This time of clear skies and calm seas was thought to be the result of a magical bird's concern for her nest. The legend explained that the female kingfisher built a floating nest on the sea during this period. She calmed the waves and winds to keep her nest safe. Borrowing from the greek name for kingfisher halky n, we call any quiet, peaceful period halcyon days.
