Nwaran (sometimes Nuwaran or Naamkaran) is a child naming ceremony celebrated in Nepal.
In the Hindu tradition, the Nwaran is celebrated on the 11 day of birth for boys & girls.
A carpeted area covered with a clean, washed cloth like a bed sheet, can be used; unless there is going to be the Havan (Homam) ceremony, in which case a fire-resistant floor is preferred.
The fruits can be used as Prasad, whilst the Puja flowers and Paan leaves are spread in the backyard near trees.
Kalash coconut, the Puja vasthra (cloth), the coins and the rice should be packed separately, and all other grains mixed together.
