%X This paper tests whether atmospheric brightness is related to Canadian birth seasonality ten-eleven months earlier. Births and visibility (brightness) are correlated nation-wide and in nine provinces/cities. For the national correlation, r=0.928. Therefore, seasonal brightness provides a plausible explanation for inter-annual changes in seasonality, and may reconcile divergent viewpoints. Easy verification is a major strength, although underlying causality remains unknown. While these results suggest a direct association between seasonal brightness and seasonality, brightness may not be an exclusive determinant.
