Answer

In Jain practice, boiled water should generally be used within the same day, and it is best to consume it before sunset.

So, if water was boiled at 8:00 AM, you should preferably use it before sunset that day.

Explanation

In Jain Dharma, water is boiled to reduce harm to tiny living beings in water. After some time, especially if left exposed or kept for long, microorganisms may again begin to develop.

Because of this, many Jain households follow the practice of:

• Boiling water in the morning
• Using it during the day
• Not using it after sunset or the next day

Takeaway

If boiled at 8 AM, use it the same day, preferably before sunset, according to common Jain practice.
