asked:
When do you start the first art challenge of each day and when do you end them each day?

Currently every challenge is on Wednesdays at 4-4:30 PM CST(Central Standard Time) and Sundays at 10-10:30 PM CST. At the 30 minute mark I open the submission box until 4:52 PM CST on Wednesdays and 10:52 PM CST on Sundays. 

Hope this helps!
