Download Android App Download iOS App Recently I made a mobile app to help me know when the Solar Noon is approaching and past. Why Is the Sun Important for Bhikkhus? Why Is The Sun Important for 8 & 10 Precepts? If you are a monk, nun or a practicing yogi who has vowed to not eat after Noon, you will benefit from this app. The real Solar Noon is not 12:00 pm when it comes to the Buddhist rules because there were no clocks back then. Rather, the Sun was used to know when one should stop eating. In addition to the Noon time, the Dawn time is important to know because that is the time at which one can start eating. If one eats before Dawn, then one is eating when it is still considered night.
