Is the banquet held on the day of celebration?

The banquet is not necessarily held on the day of the celebration.

"Wedding banquet generally refers to a celebration party held by a crew to celebrate the successful completion of the filming task after the filming of a movie or TV series is completed.

The crew is like a big family. In order to thank all the crew members for their hard work and all the actors for their wonderful performances, the producers are full of gratitude and will give you red envelopes and organize a grand wedding reception. "
