Report looking back a set number of days

Report looking back a set number of days

Hello,

I'd like to craft an event report which looks at what has happened during the last 8 days. Could you please indicate what is the code I can write in the custom criteria? I see things like [$today] or [$todayminus], but nothing for a number of days/weeks/months.

Thanks a lot,
