Not really.. What sanjeev11 is trying to point out is "Jai Ho was just another Friday release with the national holiday being wasted as it fell on Sunday. Don 2 cannot be termed as non-holiday/non-festive release due to the overall period of release i.e. December."
In other words comparing Don 2 with Ghajini, Dabangg 2 & Dhoom 3 is fine. But not with a January release when you're talking in terms of holiday/non-holiday release.
