Attached you may find a scripture in regard of the calculation of the Uposatha Days incl. Tabel of the singe days for the year 2500 - 2599 BC.
The document incl. also history and extended explainings about the calculation connected with the Khmer lunar Calender.
The file is a rar-file, named as .zip incl digital pictures of the document. It would be good to have it in digital form as well it would be goof if it would be translated into a European language.
