I'd like to know the answer to that one, too. I have found a change in the morning around 10:30 EST and then there have been days that I didn't see a change until late in the afternoon. If I had to guess, I'd say it was not automated for a certain time, but I surely do appreciate whomever does share these designs with us.!

You've got me. I usually find the update is complete by 10:00 pm MST, but that is the only time that I am usually able to get online (I have a small child). I completely agree with jrob in gratefulness for the freebies offered. =]

I have seen the new designs on as early as 10:00 EST and as late early afternoon. It is best to just check a few times until they are up. They are just marvelous and well worth the wait....
