In Jainism, the Panchkalyanak are the five auspicious events that mark the important stages in the life of a Tirthankara. For Lord Mahavir, the 24th Tirthankara, the Panchkalyanak are:

1. Chyavan Kalyanak (Conception): The auspicious moment when the soul of Mahavir entered the womb of his mother, Trishala Devi.

1. Janma Kalyanak (Birth): The auspicious birth of Mahavir at Kundagrama (near Vaishali), celebrated as Mahavir Janma Kalyanak.

1. Diksha Kalyanak (Renunciation): The event when Mahavir renounced worldly life to become an ascetic in search of spiritual truth.

1. Kevalgyan Kalyanak (Omniscience): The moment when Mahavir attained Kevalgyan (omniscience or absolute knowledge) after deep meditation and austerities.

1. Nirvan Kalyanak (Liberation): The ultimate liberation (moksha) of Mahavir from the cycle of birth and death at Pawapuri, achieving eternal bliss.

These five events are central to Jain worship and are celebrated through rituals, prayers, and festivals, especially in the context of Tirthankaras.
