Kharagpur Onsite

This page ( http://www.codechef.com/icpc/2015 ) says the kharagpur onsite contest will be held on December 10-11 2014. Is this information correct ?

You can visit official site(http://acm.iitkgp.ac.in/) for more information.

So helpful! BTW it seems the official site says another thing! and AFAIK they will change the date. But I need correct information!
