The Five Kalyanakas
| Kalyanaka | Tithi | Nakshatra |
|---|---|---|
| Chyavana (conception) | Shravana Shukla 2 | Magha |
| Janma (birth) | Vaishakha Shukla 8 | Magha |
| Diksha (renunciation) | Vaishakha Shukla 9 | Magha |
| Kevala Jnana (omniscience) | Chaitra Shukla 11 | Magha |
| Nirvana (liberation) | Chaitra Shukla 9 | Punarvasu (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 Magha, and only the nirvana shifts, to Punarvasu. This holds across the tradition, and we map it in full on the kalyanaka calendar.
What the Tradition Records
The classical biographies preserve Sumatinatha’s kalyanaka dates, lineage and iconography with care, but comparatively little narrative. We would rather show you the verified record above than pad it with invented incident. If you know of sourced material from a sangh publication or a classical commentary we have missed, tell us and we will add it with the citation.

His Birth Star, and Yours
Sumatinatha was born under Magha, in Simha. 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.
Sources. 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. Corrections are seva: tell us.
