There are a number of communities in Tamil Nadu. However, in case of every community, a Brahmin priest called upon to preside over the wedding rituals. Though there are variations in the rituals followed by different communities, the basic guidelines remain the same.

Generally Tamilians conduct marriages in public halls especially constructed for the purpose.

As per the Hindu calendar, barring the months of Aashad, Bhadrapad, Shunya, all other months are considered to be auspicious for marriage, as with most other Hindu weddings.

Tuesdays and Saturdays are not auspicious for weddings and so are Rahu Kalam and Yama Kandam. So the wedding time is fixed accordingly.

The bride's birth star is used to fix the most appropriate date and time for the wedding.
