I think a week should be for this
campaign will be Round: 23/7 - 29/7 instead of Round: 23/7 - 30/7. If it is a typo mistake then please edit it, thank you.
Each week runs from Tuesday to Monday, so the information is correct, shasan.
Each week will run from Tuesdays to Mondays, cut-off is on Mondays at 23:59:59 according to my timezone (CET).
30th July is Tuesday and if 23rd July to 30th July then it will be 8 days.
