Sir you are right. the management is run by ignorant like me.
Actually the namaz was planned in a park. And there were electronic signs every where at entrance with eid greetings and welcome message. Just 20 minutes before namaz a 20% thunderstorm turned into 100 % and everyone started running towards mosque. Looks like they fixed an older banner without looking into the date *picked up from storage. Because in the park the banner was with the current date. Someone over looked this. I will convey your comment to the director of Muslim Centre after Friday prayers this week.
Muslim Centre is not under ICNA.. this is privately managed and funded by local muslim community.
