Answer

The eighth tithi is called Ashtami.

In the Jain calendar, Ashtami means the 8th lunar day of either:

• Shukla Paksha – the bright half of the lunar month
• Krishna Paksha – the dark half of the lunar month

Explanation

A lunar month is divided into two halves:

• 1st to 15th tithi in Shukla Paksha
• 1st to 15th tithi in Krishna Paksha

So the 8th tithi in each half is known as Ashtami.

Spiritual Understanding

In Jain Dharma, certain tithis such as Ashtami, Chaturdashi, Poonam, and Amas are considered spiritually significant. Many Jains observe special practices like:

• Samayik
• Pratikraman
• Upvas or Ekasana
• More focus on prayer and self-discipline

Takeaway

The eighth tithi = Ashtami, an important lunar day for spiritual reflection and Jain religious observance.
