Usually I use "next 3 weeks" for my Google Calendar view. That gets about the right number of slots for the eighteen calendars I either maintain or monitor. But in the next few days there are too many places where I have five things going on at once . And I don't just mean 5 all-day entries on the same day. I mean 5 timed entries all running at 2:00 on Saturday.
So far, "next 5 days" is holding up OK. We'll see if I have to make the window even shorter.
