Jain dharm ke anusar, har Tirthankar ke jeevan me paanch vishesh pavitra ghatnayein hoti hain jinhe "Panch Kalyanak" kaha jata hai. Yeh paanch Kalyanak nimn hain:

1. Chyavan Kalyanak: Tirthankar ka garbh mein aana (conception).
2. Janma Kalyanak: Tirthankar ka janm (birth).
3. Tap Kalyanak: Tirthankar ka balyaavastha mein hi tap (austerities) aur vairagya ki or agrasar hona.
4. Kevalgyan Kalyanak: Tirthankar ko keval gyan (absolute knowledge) prapt hona.
5. Nirvan Kalyanak: Tirthankar ka moksha prapt karna (liberation from the cycle of birth and death).

Yeh paanch kalyanak har Tirthankar ke jeevan me hote hain, aur inki yaad me Jain samaj vishesh anushthan aur pooja karta hai.
