Shopkeeper Challenge Question

I think what the OP is asking is, for each individual day's task, do you have to complete it in a 24 hr period from when you started it in order for it to count? Since the only timer showing is the countdown until the next set of challenges starts, I would say that the previous answer is still correct, in that as long as you have finished all tasks before the next week's set starts, you're good.

Others have mentioned that you can do them out of order, which I take to mean that you can start the first day's task, not finish it the first day, start the second day's task, finish the second day's task, then finish the first day's task and it all still counts. Can anyone verify this?
