Hello there! I am interested in precision bazi calculation so i do think that RST has logic . How this affects Bazi is a interesting question, since most modern bazi professional practitioners use the classic approach.

Most of the times applying RST will sift your hour pillar by one hour if one uses the 24 1 hr timezones standard. But in the real world , timezones arent geographically the same in shape.  Depending on the wideness of the timezone area this can vary  as you can see on this attached timezone map, some timezones are huge, like for example china's timezone. Then as timezones arent uniform , the RST formula needs to take this into consideration? Or is there a database to know longitude of the center of each timezone not based on the homogenous 1hr per 15 deg convention.

I appraciate any help on this! 

I have come accrosss Joey Jap 's video on youtube speaking about RST in bazi here:

I did not quite understand him very well, but his point is that using RST is an option, and that it does not affect BAZI interpretation , but I kind of think he contradicts himself. He claims that westerners have a more fixed engineer type way of thinking and that they need more precission, but he uses the point that the Divine as he calls it does not use RST , or so I understood.

I really have some doubts about his arguments , but what is really important is the empirical facts. If one individual's chart shows for ex fire goat in the birth hour, this should affect his relationships and life events regarding children relatives or child events , but then applying RST will depeding on the longitude of birth  make his hour pillar to shift drastically away from that .

So in order to verify the effect of RST divergence to standard timezone times, one needs to do due diligence and study at least 100 bazi charts, better if omre, to obtain accurate statistics that show some kind of deviation regarding the factual children relationships.

Am I missing something out? I probably am, since I am not really a bazi practitioner, but an indpendent astrology researcher.

Hi Momotaro,

This is fairly simple.

Pick 100, 200, 500 people. Get their birthdays and birth times and plug that into the King poem.
You will be able to determine how accurate the poem is.

bazi-calculator.com has a database of thousands of people and birth data.

All the best.

She is importing garment products from overseas. And yes, she is a parental figure in my family and i considered her as a mentor since she and her husband have a lot of experiences in business. I'm hoping that this could be a turning point of my life. So it seems it kinda match what you saw in my chart? That my source of my income would come from overseas?

The whole situation generally matches what I see, if it clears any doubt.
