Answer

If you are asking from a Jain Dharma / astrology / muhurat point of view, there is no single rule that “the 8th month is always bad” in Jain tradition.

But your question is unclear. Do you mean:

• 8th month of pregnancy?
• 8th month for marriage or engagement?
• 8th month for house shifting, business, travel, or ceremony?
• 8th lunar month in Jain calendar?

Jain Understanding

In Jain Dharma, the main focus is on:

• Ahimsa
• Right conduct
• Purity of intention
• Avoiding unnecessary harm
• Following vows and discipline

For specific timing like marriage, griha-pravesh, or other rituals, families often consult their tradition, elders, or a knowledgeable Jain pandit.

Takeaway

Please tell me what “8th month” refers to, and I can answer more clearly from a Jain perspective.
