Namaskaram. Andal thiru kalyanam is celebrated on bhogi day in all temples. Really is that the day Andal thiru kalyanam. Because I remember my grand mother saying after margazhi month she did kamadeva pooja and other vrathams and then she went to srirangam along with his father perialzhwar, I am not sure how for it is true. I see andal kalyanam in sri rangam also on bhogi day so having curiosity to know further.
