Here are the day-names for Paryushan in the two main Jain traditions:

• Digambar tradition (Das Lakshan Parva – 10 days)

1) Kshama (Forgiveness) 2) Mardava (Humility) 3) Arjava (Straightforwardness) 4) Shaucha (Purity/Contentment) 5) Satya (Truth) 6) Samyam (Self-restraint) 7) Tapa (Austerity) 8) Tyag (Renunciation) 9) Akinchanya (Non-attachment) 10) Brahmacharya (Celibacy)

Each day is dedicated to one supreme virtue, with related practices. ( parasnathjainsociety.org, jainknowledge.com)

• Shwetambar tradition (Paryushan Parva – 8 days; Samvatsari is the 8th day)

The eight days are observed as a sequence of spiritual practices; the most important day is the 8th, Samvatsari (the day of forgiveness). The days themselves aren’t traditionally given separate names like the Digambar Das Lakshan Parva; they are referred to by their order (1st day, 2nd day, ..., 8th day). ( jainknowledge.com)

If you’d like, I can also share the exact dates for a given year or how these days are observed in a specific sangh.
