Janm Kalyanak (janmdin) Jain dharm me har Tirthankara ke janam din ko vishesh roop se yaad kiya jata hai. Yahan “Janm Kalyanak” ka matlab hai 24 Tirthankaro ke janam avsar ki ujjain yaad ki jati. Har Tirthankara ke janam ki kahani aur uski aisi-kaisi dharmik ghatnayein Jain granthon me varnit hoti hain.

• Samanya roop se: Janm Kalyanak par bhakti, tapasya, aur aarti-ceremony hoti hai. Kuch sampraday (Digambar ya Shwetambar) me janm-kalyan ke din aur ritirivaazon me chhoti-moti vidhi-vibhed ho sakte hain, lekin mool arth aur dharmik uddeshya ek hi hota hai: Tirthankara ke janam ki pavitra yaad-daar.

• 24 Tirthankara: Jain dharm me kul 24 Tirthankara maane jaate hain. Inme se pratham Adinath (Rishabhanatha) se le kar antim Mahavira tak ke janam kalyan ki kahaniyon ka ullekh milta hai.

Yadi aap kisi vishesh Tirthankara ki Janm Kalyanak ki vistrit jankari chahte hain (jaise ki kis tithi ko manaya jata hai, janam sthal, ya us din ki vishesh kriya), main us Tirthankara ke sandarbh me spasht arth aur parampara ke anuroop details de dunga.
