In Jainism, Pārṇā refers to the act of breaking a fast, especially after observing major fasts like Paryushan or Ayambil Oli. Traditionally, it is recommended that Pārṇā should be completed within 48 minutes (one muhūrta) after the prescribed time to break the fast. This timing is considered auspicious and follows the Jain tradition.

Summary: Pārṇā should ideally be completed within 48 minutes (one muhūrta) after the appropriate time for breaking the fast.
