It matter on which film one is talking. An event film will be effected by ₹2-3cr on a normal match while ₹4-5cr on a big match. For T20 match effect will be about half what I said above.
While for a small film effect will be ₹0-2cr.
Big Cricket Match like of World Cup (Non-Holiday)-4 Cr Holiday-6
Normal Match(Non-Holiday)-1.5 Cr Holiday-2-2.5 cr
Depends On Whose Film Has Released. It Won't Affect An Aamir Khan Film. But It Will Affect Shahrukh's Film.
