[jaibabu]

Dear sir,

Could you please suggest me that keeping gruhapravesam and Valaikappu on August or September 2016 (AAVAni month). We plan to keep gruhapravesam and Valaikappu on September 5th 2016 (on Vinayagar chaturthi). Is it good day to keep functions in this month? Could you please suggest me the good day for Gruhapravesam and Valaikappu. (Since, from August 17th to September 17th it is 9th month of pregnancy. We plan to keep it now).

Please give me the clarification, that shall we go ahead and do these functions

Thanks
