I believe there’s some muslim “holy” day that was celebrated on the 11th. I think we were all warned that we should in no way misinterpret their celebrations as being rejoicing over 9/11. Being a devout muslim before anything else, that’s likely what Huma chose.
No, the EID holiday fell on the 12th this year. There was some doubt before because it depends upon their goofy moon calendar for the exact date each year, but the committee of grand poombahs in Saudi Arabia announced it would be on the 12th.
