In Jainism, the Siddhachakra Pujan is a significant and auspicious ritual. Traditionally, there is no strict, universally mandated time for performing Siddhachakra Pujan, but some common practices and guidelines are observed:

Preferred Time

• Morning: The most auspicious time to perform Siddhachakra Pujan is in the morning, preferably after taking a bath and wearing clean clothes, as this aligns with the general Jain practice of starting spiritual activities with purity and freshness.
• Auspicious Days: Many devotees choose to perform Siddhachakra Pujan during Parvadhiraj Paryushan, Ayambil Oli, or on other special Jain festivals, birthdays, anniversaries, or whenever a special blessing is sought.

Temple or Home

• The pujan can be performed either in a Jain temple or at home. At home, it is recommended to do it in a clean, peaceful place dedicated to spiritual activities.

Additional Notes

• Niyam (Vow): Some people do the Siddhachakra Pujan as a niyam (vow) for consecutive days, especially during Ayambil Oli (for 9 days).
• Consultation: For community or group pujans, consult your local Jain temple or a knowledgeable Jain practitioner for specific timings or additional rituals.

In summary: Siddhachakra Pujan is best performed in the morning, especially on auspicious or significant days, but can be done at any clean and peaceful time according to your convenience and intent.
