Answer

In Jain practice, Labdhi Tap is generally observed as a 51-day tap.

The common count is:

• 25 Upvas
• 26 Ekasana

So, in total:

• Total days: 51
• Upvas: 25
• Ekasana: 26

Explanation

Labdhi Tap is usually done by alternating:

• One day Ekasana
• Next day Upvas

Since it begins with Ekasana and ends with Ekasana, the number of Ekasana becomes one more than Upvas:

• 26 Ekasana
• 25 Upvas

Takeaway

Labdhi Tap is a serious Jain tapasya and should be undertaken with proper guidance from a Guru, sadhu-sadhvi bhagwant, or experienced Jain shravak-shravika, according to one’s health and capacity.
