Re: Day after shaadi..
Depends on family traditions. Usually a big breakfast (sometimes with both the grooms and brides side), sometimes only the grooms side).
One relatives next day was the most ideal! Both sides together for a big brunch then just hanging out and relaxing the entire day. Some people make it an “event” day–maybe singers performing…traditional music…etc etc
Some families have the valima the next day (if they was the wedding all in one weekend).
