In Jain tradition, the Tirthankar is not decided by your date of birth (like a zodiac sign).

Every soul can worship all 24 Tirthankar Bhagwans. Many families choose:

• Their kuldev / kuldevi (family deity), or
• A favorite Tirthankar (e.g. Mahavir Swami, Parshvanath, Neminath, Adinath),

based on family tradition or personal devotion – not based on birth date.

Some local customs loosely “match” nakshatra or dates to a Tirthankar, but this is not from main Jain Agams; it is just social practice, not a scriptural rule.

If you tell me:

• Your tradition (Digambar / Shwetambar), and
• What exactly you want (e.g. “Which Tirthankar should I keep as my ishtadev?”),

I can suggest a simple, dharmic way to choose your ishta Tirthankar while keeping full respect to Jain scriptures.
