Answer

“Ek tithi” and “be tithi” are usually not two different Jain doctrines. They are different calendar traditions used to decide the date of a vrat, festival, or religious observance based on lunar tithis.

Explanation

• Ek tithi: the observance is counted according to one tithi on a given day.
• Be tithi: the observance is decided using a different panchang rule when a tithi overlaps two sunrises or two calendar days.
• So the difference is mainly about how the lunar date is calculated, not about the core teachings of Jain Dharma.

This is why different Jain communities may observe the same festival on slightly different days.

Who is right?

In Jain Dharma, this is generally a matter of tradition and panchang calculation, not one side being “right” and the other “wrong.”

• If a community follows a particular guru-parampara, sangh, or panchang, that method is considered correct for that community.
• Spiritually, the more important thing is bhav (inner sincerity), ahimsa, and right conduct.
• Jain Dharma does not encourage ego or conflict over calendar differences.

Spiritual Understanding

The essence of Jain practice is not winning a debate about dates, but deepening:

• samyak darshan
• samyak jnan
• samyak charitra

So, both traditions can be respected when they are followed with sincerity and without disrespect for others.

Takeaway

“Ek tithi” and “be tithi” are usually different ways of counting time, not different Jain truths. The right observance is the one accepted by your own Jain tradition and followed with devotion.
