Answer

The tithi system is the Jain way of counting time according to the lunar calendar. A tithi is a lunar day, and Jain festivals, fasts, and observances are often based on tithis rather than fixed dates in the English calendar.

Explanation

In this system:

• The moon’s movement is used to measure time.
• One lunar month is divided into two halves:

- Shukla Paksha — the bright half, when the moon grows - Krishna Paksha — the dark half, when the moon wanes

• Each half has 15 tithis, so a lunar month has about 30 tithis.

Common tithi names include:

• Pratipada — 1st tithi
• Dwitiya — 2nd tithi
• Tritiya — 3rd tithi
• ...
• Purnima — full moon day
• Amavasya — new moon day

In Jain tradition, many important observances are connected to specific tithis, such as:

• Paryushan
• Ashtami
• Chaudas
• Purnima
• Amavasya

Because the lunar calendar moves differently from the solar calendar, Jain tithis do not always match the same English calendar date every year.

Spiritual Understanding

The tithi system is important in Jain Dharma because it helps devotees:

• follow traditional observances with accuracy
• maintain discipline in spiritual life
• remember sacred days connected with fasting, prayer, and reflection
• live in harmony with the natural rhythm of the moon and time

It also teaches us that spiritual life is not only about convenience, but about awareness, discipline, and tradition.

Takeaway

A tithi is a lunar day, and the Jain tithi system is the traditional calendar used to observe festivals, fasts, and holy days. It is an important part of Jain religious life and practice.
