Hi Dylis Cai Meng
The tong shu for 2013 is not out yet and i can only check after it is out (after 7th lunar mth). Right now only way is use bazi to calculate the dates, whcih is the right way
Anyway,groom is born in Pig yr, and 2013 snake yr clashes with Pig, hence a bad yr for wedding. U might have to look at 2014 instead
