I see I didn't receive stakes for previous week, I don't see any rule about start or end day of the week except these rules:
Reports for the week are on Tuesday 23:59
Please see terms and conditions for more information.
And I checked again spreadsheet but there it says first week was 03 - 09 but Tuesday 23:59 is 10. 07.
It confused me because thread is contract between users and/or bounty manager and/or project and spreadsheet is only for stakes counting.
However, this won't make too much difference at the end of the campaign, just saying, maybe to update signature campaign and add last day of the week
