agnes, the websites must take with a pinch of salt. not entirely sure wat they are based on but seems like they follow tong shu. and the dates given to you by the geomancer relate to you and your FH’s ba zi, which means it is calculated for you 2 only. This is more accurate as it takes into account your actual time and date of birth, etc. The tong shu only provides a guidance of good dates which may not necessarily be tat good for you and your FH. On the converse, it doesn’t mean tat a “bad†date is bad for you and your FH as tat is based on your personal details. There have been many cases of the other BTBs whose dates given “clash†with tong shu but this doesn’t mean it is bad. like for me, my date also clashes with the tong shu but supposedly it is a very good day for me and my FH.
