On the day of Nag Panchami, one should get up early in the morning and finish bathing. Then take a bowl of milk to a nearby Shiva or Murugan temple and give for abhisheka. Then after returning from the temple, the devotee may have the milk as prasad. The rest of the day should involve prayers to Lord Shiva or Lord Murugan.
