In hindu weddings, a roka ceremony is performed where the girl and the boy are considered to be engaged and allowed to court each other. After this ceremony, they are not allowed to consider other matches for marriage. The wedding date is fixed after roka. 

The roka ceremony is performed at an auspicious time (Muhurat time advised by Shubhpuja experts) which is determined as per the horoscopes of the bride and groom and favourable planetary positions. At this function, a gauri ganesh puja havan/homam for the happiness of the couple is performed.
