If i donated Monday, which is the first day of the week, can i come back on Wednesday, 2 days later, or Thursday, 2 days in between?? I always thought that if you donated on Monday, then Wednesday was your next day.

One complexity to add is that there must be a week between the next "set" of donations. Example: if you donate on Thursday and Sunday... the next week you can't donate on Wednesday. You can move to Friday and still do Sunday... but once you do this you can't move back to Thursday (or any other day) without skipping a donation.

Wednesday would normally be the next time you can donate unless stated otherwise.

Yes. You could donate again on Wednesday.

Yes I donated Monday and am back wed has been like that Everytime I've ever went
