Answer

In the Jain calendar, Paryushan is generally observed from Day 42 to Day 49 of the 51-day period.

So, from Day 1 to Day 51, the Paryushan days are:

• Day 42
• Day 43
• Day 44
• Day 45
• Day 46
• Day 47
• Day 48
• Day 49

Explanation

Paryushan is an important Jain festival of inner purification, repentance, forgiveness, self-discipline, and spiritual reflection.

For Shwetambar Jains, Paryushan is traditionally observed for 8 days.

Takeaway

From a 51-day count, Paryushan = Day 42 through Day 49.
