Both films are slated to release Jan 23, 2015.
"'Baby' is looking good, but both the films are of different genres. I think this was the ideal date for 'Dolly Ki Doli'," Arbaaz said at an event here.
He spoke at the trailer launch, which was held Friday, his wedding anniversary.
At the conference, Arbaaz's father and veteren writer Salim Khan was present too, and he said that the former has produced "Dolly Ki Doli" sans any family support.
"In this industry (Hindi film industry), Arbaaz supported so many people and he was called as a supporting actor, but for this film, he has not taken any support from his family. This is his film," said the proud father.
To that, the humble Arbaaz said: "They would like to believe that they didn't support me, but they are always there for me."
"Dolly Ki Doli" is directed by Abhishek Dogra.
