For the weekly deposit limit, is there a time when the week begins and ends? Or is it a limit on any 7 day period? I am trying to figure out when I will be able to deposit again.

It's a complete guess, but I think it would function relative to a 7-day time period from the exact time of your deposit that hits your limit. If the 7-days were to just start the day of you reaching your limit I think it would be relative to GMT time. Hope that helps.
