Hi I'm pretty new at this and have a few questions. Why are all of the Uposatha calendars different and would it be wise to just observe the 8 precepts on the exact dates they occur according to the astrological calendar for my specific time zone?
If yes, then say a full moon were to be at 1:00 AM. Would you have observed the precepts the day before or after the sun rises later in the day?
If no, which calendar should I use and why?
I'm just a bit confused and I would appreciate any help.
Thank you.
