The neiros (Chanukah lights) illuminate the darkest season of the year. This is the only holiday that begins during the period of the waning moon. The days of Chanukah actually become darker and darker ... until the very end, because Chanukah ends just when the sliver of the New Moon is becoming visible in the night sky.
