The Call of Duty ELITE twitter feed answered this 11 Jun. It said (in answer to someone's same question about the times) "Currently, Clan Ops are on a weekend cadence to accommodate international clans." So I guess Europeans love playing Monday mornings from midnight to 3am.

the clan ops are starting to do my head in, first im bored of them, the same things week after week after week!? Seriously?

As for Accomodating International Clans, im in the UK, do they not know i just LOVE to play CoD at 2am until 5 am on a saturday morning, and then 7pm until 10pm on a saturday night!?

Was hoping it would change up a bit soon, but they posted next weeks as well and its the same!

Ive asked them about this a few months back, why all the clan ops start within the same 6 hours everyday, since most of my clan worked the same shift during those clan ops.  they told me they would be moving it to the weekends for international clans.  so now they all start within the same 4 hours a day only 3 days a week.  instead of expanding it, they restricted it.  I hope you dont have to work on the weekends lol.

Well we are down to two weeks of clan ops so they will be adding more soon..I figured id bring this subject up again , hoping to see them add some weekday ops !!!

I agree with OP that every other day would be a good idea and would let everybody play.Not just the players that have weekends off work and the others that like sitting around the house on weekends.
