Well, ur wedding has been bring forward early. Much have lot of preparation to be done. Is the banquet allow u to do so?
If i did not remember wrongly, this year have 2 May in chinese calendar, so it defintely will delay the Month for next year. And according to my Master 3 Apr 2010 (my AD) is "Guan Xin" birthday, so i guess ching ming shouldnt fall on that month? Not too sure about it.
