Speaking of the auspicious choice of the ecliptic, it has little to do with Buddhism. Choosing dates and geomantic omen is a matter for Taoism. It is important to urge auspicious days to avoid space and make rational use of it.
When you get married in Bhutan, you should choose the right date, check the date of birth, and more importantly, have a premarital examination, because everyone's birth time is different, which means that everyone's numerology and fate are different, which contains five elements that help each other.
