Answer

In Jain practice, doing 2 Upvas and 6 Ekashna together is generally called a form of Tapasya.

There is no single special fixed name for exactly 2 Upvas + 6 Ekashna that is universally used in Jain tradition.

Explanation

• Upvas means fasting for the day, generally without food.
• Ekashna means eating only once in the day, within proper Jain rules.
• When these are done together over several days, it is called Tap or Tapasya.

Some people may describe it simply as:

• 2 Upvas ane 6 Ekashna ni Tapasya
• 8 divas ni Tapasya, if it was done over 8 days

Takeaway

You can correctly say: “I did 2 Upvas and 6 Ekashna ni Tapasya.”
