In Jainism, there are specific guidelines regarding the timing of eating and sleeping to support the principles of ahimsa (non-violence), self-discipline, and spiritual progress.

Eating:

• Jains, especially those who are more observant or follow monastic practices, avoid eating after sunset. This is to minimize harm to microorganisms that become more active at night and to aid in digestion and spiritual alertness.
• Ideally, food should be consumed during daylight hours. Many lay followers (śrāvaks/śrāvikās) finish their meals before sunset.
• Monks and nuns (sādhus/sādhvīs) are stricter and usually eat only once or twice before noon.

Sleeping:

• Jain teachings encourage maintaining a regular and disciplined schedule.
• Sleeping early, preferably soon after sunset and after completing evening prayers or meditation, is advised.
• Avoiding late nights helps maintain self-control and keeps the mind and body pure for spiritual practices.

Summary:

• Eat only during daylight, ideally finishing your last meal before sunset.
• Try to go to bed early, after performing your spiritual practices in the evening.

These practices are intended to support non-violence, discipline, and spiritual focus in daily life.
