I found that a 43 folders concept didn't work for me & my wife. We discovered that we needed to see an overview of what was coming up, rather than only discovering something on the day.
So after a few experiments we came up with a large pin board, on which we have created labeled areas.
Basically a column for this week, labeled "This week", with rows for each day of the week.
A column for next week, labeled "Next Week" again with rows for each day of the week.
A third column with two rows, one labelled "Soon" (anything happening sometime in about the next two weeks after next week) and the other labeled "Later".
Then once a week (Sunday evening works best for us), it's my job to move everything from Next Week to This week, find anything on Soon with needs moving to Next Week and similarly moving anything from Later to Soon.
