Hi Losh2090,
To answer your qns:
1) Is it true that we can't hold any customary wedding in the year of Tiger?
Definitely not true. I've posted an explanation of this sometime back in this forum, so you might want to do a search on it. In brief, this is pure superstition. Only those born in Monkey year are not suitable. As for the rest, all you need is to find a good date. Reason why elderly says that Tiger yr is no good coz they associate the characteristics of tiger to the year. There is no logic or basis to this. Every year can be good or bad depending on your Bazi. Even dragon yr can be bad! If dragon yr is really 100% good, then there should not be any divorce for those that got married in dragon year right? We all know this is not the case...
2) Normally what are the informations require for choosing customary wedding date?
You will need the couple's birthday and time of birth (according to birth cert), parents animals signs and when you want your wedding to be held.
3) What does the Bazhi refering to? Is it the lunar date of birth and also time of birth??
It refers to your birthday and time of birth (according to your birth cert). Bazi is not derived from your lunar birthday. This is s HUGE misconception! All Feng Shui, Bazi and Date Selection uses the Solar Calendar (Wan Nian Li), not the Lunar Calendar! Using the lunar calendar to plot a Bazi chart is wrong. So all we need is just your normal georgian birthday and time of birth, and I will do the conversion.
4) Is 29 Sept 2009 a good / auspicious date for ROM?
For general tong shu date, i will need the animal signs of both of you and your parents's before i can check for you.
Hope this helps
