Answer

Yes, in Sthānakvāsī Jain tradition, Pucchisunam / Pucchisuṇam can generally be recited after sunset, especially as part of Pratikraman or devotional recitation.

Explanation

In Jain practice, the main restriction after sunset is usually related to activities involving possible harm to living beings, such as eating, drinking without proper discipline, or careless movement. Reciting a sutra, stavan, or prayer is a spiritual activity and is not considered harmful.

However:

• If your family, guru, or local Sthānakvāsī tradition follows a specific rule about when certain sutras should be recited, you should follow that guidance.
• Some recitations are traditionally done within a particular ritual sequence, such as during Pratikraman.
• Pronunciation and bhāv — inner reverence — are very important while reciting sacred text.

Spiritual Understanding

Reciting Jain sutras after sunset can support calmness, repentance, reflection, and awareness of the soul. If done with humility and right intention, it becomes a form of dharma ārādhana.

Takeaway

You may recite Pucchisunam after sunset, but if you are following a specific Sthānakvāsī guru-paramparā, it is best to confirm with your guru or learned elder for the exact practice.
