Śvetāmbara Jain tradition does not have one single universally fixed Panch Kalyanak tithi table across all groups, because the tithis can differ by panchang / nirnay and even within Śvetāmbara usage. ( jainknowledge.com)

So, I don’t want to give you a full 24-Tirthankar list unless it is verified for the exact Śvetāmbara calendar you mean. What I can confirm from a Jain source is the Mahāvīr Janma Kalyanak as Chaitra Shukla Trayodashi. Jain tradition also commonly remembers Mahāvīr’s Nirvan Kalyanak on Kartik Krishna Amavasya.

If you want a complete table, the safest Jain way is to use the specific Śvetāmbara panchang followed by your sangh, because the month/tithi mappings are not identical everywhere. ( jainknowledge.com)

What I found was enough to confirm the important point about variation, but it was not sufficient to verify a single complete Śvetāmbara table for all 24 Tirthankars without risking an incorrect list.
