Answer

In Jain tradition, a day and night together are divided into 30 muhurtas:

• 15 muhurtas of daytime
• 15 muhurtas of nighttime

Each muhurta is generally understood as 48 minutes.

However, Jain Dharma does not commonly define all 30 muhurtas as a fixed universal timetable such as:

• 1 muhurta only for lunch
• 1 muhurta only for dinner
• 2 muhurtas only for meditation
• and so on for all 30

Rather, Jain practice gives importance to using time in a spiritually disciplined way.

Explanation

In Jain conduct, time is generally organized around religious discipline, such as:

• Sāmāyika – practice of equanimity, traditionally for one muhurta
• Pratikramaṇa – repentance and self-reflection
• Svādhyāya – scriptural study
• Dhyāna – meditation
• Āhāra – taking food with awareness and restraint
• Pratyākhyāna – taking vows or renunciations for a period of time

For householders, Jain Dharma emphasizes:

• eating with restraint, not indulgence
• avoiding food at improper times, especially after sunset in stricter practice
• setting aside time for sāmāyika, pratikramaṇa, pūjā, svādhyāya, and meditation
• reducing unnecessary worldly activities

But there is no single standard list accepted across Jain tradition that assigns every one of the 30 muhurtas to a specific activity like a daily schedule.

Spiritual Understanding

The Jain view is not merely “how many muhurtas for each activity,” but:

• How much time is spent in samyak bhāva — right inner attitude?
• How much time is used for reducing kaṣāyas — anger, pride, deceit, and greed?
• How much time is used for ahiṃsā, saṃyama, tapas, svādhyāya, and dhyāna?

A person may eat in a short time but with restraint and awareness, while another may meditate for longer but with distracted thoughts. Jain Dharma values the purity of conduct and inner state.

Takeaway

There are 30 muhurtas in a full day, but Jain Dharma does not prescribe a fixed activity chart for all 30 muhurtas for everyone.

The clearest traditional example is that one sāmāyika is for one muhurta, and the broader guidance is to use more and more time for self-restraint, reflection, study, meditation, and spiritual purification.
