Shri Radha Krishna Gannodesha Dipika by Shrila Rupa Goswami.
Shrimati Radharani's glorious birth occured on the eighth day of the bright moon in the month of Bhadra. Although generally not full on that day, the moon appeared full to celebrate Radharani's appearance in this world.
Ideally one should either total fast or fast from grains etc. for the full Shri Radhashtami Tithi from sunrise to sunrise next day. But some fast only till noon on Radhashtami stating that Shri Radha appeared at noon so they can have a feast at noon.
