Answer

For peda made with milk powder, ghee, sugar, kesar, and milk, the kaal period is generally counted as the same day only for Jain eating discipline, because it contains milk and is a cooked/prepared sweet.

If you are doing ekashna, it is best to eat it within your ekashna time on the same day it was prepared.

Explanation

In Jain practice, foods containing milk or milk-based ingredients are usually treated with extra care because they can spoil and develop subtle life forms more quickly.

Since your peda contains:

• Milk powder
• Milk
• Ghee
• Sugar
• Kesar

it should not be treated like a long-lasting dry item for religious eating purposes.

For Ekashna

During ekashna, the safest religious practice is:

• Prepare it fresh
• Eat it in the same sitting / same eating period
• Avoid eating it later after the ekashna is over
• Avoid keeping it for the next day

Takeaway

For your ekashna, consider the peda’s usable kaal as same day, preferably within the ekashna eating time. If you follow a specific gacch, sampraday, or guru’s maryada, follow that guidance first.
