In Jainism, "Choviyaar" (also spelled as chauvihar) refers to the practice of not eating or drinking anything from sunset until after sunrise the next day—essentially, complete fasting at night.

"Chaumasi Chaudas" is a religious observance that occurs every four months (chaumasi = four months, chaudas = fourteenth day of the lunar fortnight), where Jains observe special austerities, pratikraman (reflection), and sometimes fasting.

There is no direct numerical equivalence between "1 choviyaar" and the observance of "chaumasi chaudas." Choviyaar is a daily practice, while chaumasi chaudas is an event observed four times a year on the 14th day of each fourth lunar month.

If your question is about the merit (punya) or importance: Jain scriptures do not provide a specific formula or multiplication of how many choviyaars equal the merit of fasting or observing chaumasi chaudas. Both are considered auspicious and beneficial for spiritual progress, but they serve different purposes:

• Choviyaar: Daily discipline, promotes self-control and ahimsa (non-violence).
• Chaumasi Chaudas: Periodic reflection, confession, and renewal of vows; often involves special fasting or pratikraman.

Summary: There is no prescribed number in Jain scriptures that equates "1 choviyaar" to a certain number of times on "chaumasi chaudas." Each has its own significance and place in Jain practice.
