In Jainism there isn’t a canonical “birthday pooja” rite. Birthdays are typically a personal or family occasion, not a scripted religious ceremony. If you want to observe your birthday in a Jain spirit, you can choose simple, wholesome practices that align with Jain values (ahimsa, truth, purification, charity).

Simple Jain-friendly birthday observance (pick what feels right):

• Start with reflection: do a short personal prayer of gratitude and vow to practice non-violence, truth, and purification in the year ahead.
• Navkar Mantra or short prayers: recite the Navkar Mantra or other short, peaceful Jain prayers to focus the mind on self-purification and non-violence.
• Samayik or Pratikraman: if you can, take a brief period of meditation or a light pratikraman-like reflection to review your actions with forgiveness and self-improvement in mind.
• Temple visit or darshan: offer a simple salutation to the Tirthankaras at a temple or at home, with a small lamp or flowers as a symbolic offering of seva and non-violence.
• Dana (charity): give a small donation or charity in the name of the day—to a Jain cause or to a charitable activity that supports non-violence and welfare.
• Ahimsa-focused actions: resolve one concrete act of non-violence or kindness in the coming year (e.g., avoiding harm to living beings, being more mindful of others, practicing truthfulness).
• Family sharing: light a lamp together, share a Jain story or teaching, and discuss how to cultivate restraint, compassion, and self-improvement.

If you want, tell me your tradition (Digambara or Śvētāmbara) and what you’re hoping to emphasize (gratitude, purification, charity, etc.), and I can tailor a short, traditional-sounding birthday observance in line with that.
