The festival of Diwali is arriving and there are many legends associated with it:

1. The first day of Dhan Trayodashi is the day when Goddess Lakshmi appeared from the Samudra Manthan. 2. Next comes Narak Chaturdashi is when Lord Krishna killed the demon Narkasur. 3. The next day of Amavasya celebrated as Deep-awali is when Lord Rama and Sita returned to Ayodhya after defeating Ravan. 4. This is followed by Govardhan Puja or Annakut on the next day. 5. The final day of the festival is Bhai-duj which is also called Yamadvitiya since it is associated with Yama, the god of Death and his sister Yamuna the second day after new moon.

Chronologically, I guess the Samudra Manthan episode could have come first followed by the Yam-Yamuna episode; then the Ramayan episode and finally the two days related to Krishna. My question is, which is the oldest reference to each of these celebrations?
