Yakhee I am Saudi and from here! Since when was Umm Al Qura calender used to determine Eid? Thats ridiculous! Every year the night before at a late time theres an announcement by the sheikhs from supreme court. Many sit by TVs and open the radios waiting for the announcement. This is common knowledge. Saying otherwise is simply a lie. And looking into that website seeing how anti salafi it is, I can see why, and that its not simply a misunderstanding.
