The Five Kalyanakas
| Kalyanaka | Tithi | Nakshatra |
|---|---|---|
| Chyavana (conception) | Vaishakha Shukla 13 | Rohini |
| Janma (birth) | Magha Shukla 8 | Rohini |
| Diksha (renunciation) | Magha Shukla 9 | Rohini |
| Kevala Jnana (omniscience) | Paush Shukla 11 | Rohini |
| Nirvana (liberation) | Chaitra Shukla 5 | Mrigashirsha (shifts) |
Months are given in the purnimanta convention, the one Hemachandra uses. For a Krishna-paksha date the Gujarati amanta name is one month earlier; Shukla dates are the same in both.
Note the pattern: his first four kalyanakas all fall in Rohini, and only the nirvana shifts, to Mrigashirsha. This holds across the tradition, and we map it in full on the kalyanaka calendar.
What the Texts Record
Hemachandra notes something unusual about the night of his birth: Sagara, the second Chakravartin of this era, was born the same night to Queen Vaijayanti. The tradition liked the symmetry of a world-teacher and a world-emperor arriving together.
At his birth the text uses a phrase we meet repeatedly in these biographies, that “the planets were in exaltation.” We examine that formula carefully on our Mahavira kundali page: it appears at seven-plus births, names no planet and gives no sign, and is a statement of auspiciousness rather than a horoscope.
His nirvana came at Mount Sammeta with a thousand ascetics.

His Birth Star, and Yours
Ajitanatha was born under Rohini, in Vrishabha. If that is your janma nakshatra too, the tradition offers a devotional kinship: his kalyanaka days, his story, his image. Kinship, not destiny.
Our free kundali tool computes your janma nakshatra and tells you directly which Tirthankaras share it. The complete cross-verified table is at the birth stars of the 24 Tirthankaras.

Kalyanaka dates and nakshatras from Hemachandra's Trishashti-Shalaka-Purusha-Charitra (Johnson translation), read chapter by chapter, with the Kalpasutra cross-checked where it covers this Tirthankara. Biographical and iconographic details follow the standard references. Where the sects differ, both readings are shown; where a source does not state a value, we say so rather than infer it.
