At the Risk of Being Repetitive...

When I look back at the past couple of months, it seems that much of the worst insurgent violence in Iraq takes place on Saturday and Sunday. It's not because the insurgent population of Iraq has nothing better to do on the weekends (idle hands, devil's playground, etc. etc.). It's because the Islamic holy day of the week is Friday, not Sunday like in Christian culture. The Islamic weekend is Thursday and Friday.

So, when you read a headline like Shiite Cleric Threatens Suicide Attacks, and you read that the instigating sermon took place on Friday, now you know why you see insurgent reaction on Saturday or Sunday.

But of course, you already knew this, right?
