Friday after 4-5 in the afternoon once you get off work/school, the whole of Saturday, and the whole of Sunday. More than two days as far as I can see. But, yeah, only two days of drinking.
Also, completely off-topic but since we're on the subject of weeks... Monday is the first day of the week. Monday is. Not Sunday. Who even came up with the ridiculous notion that Sunday starts the week? Like, what the hell? That makes no sense whatsoever. The "weekday" -part of the week is Monday through Friday work hours, and the "weekend" -part of the week starts on Friday after work hours and ends on Sunday.
