Sunday to Thursday

Once again I find myself sitting in the office on a Sunday while most of my colleagues are getting ready to enjoy the second day of their weekend. This whole having a weekend on Friday and Saturday isn't really working too well for me. I don't really have Friday off because the rest of my offices work on Friday and I have a conference call every Friday evening. So, in the end, I am left with one day, Saturday, where I am on the same page as the rest of my colleagues.

So why is the work week Sunday through Thursday in most Muslim countries? I don't know yet, but I shall find out. I would at least like to find out why I am sitting in the office on a Sunday the next time I'm here.
