Simple Default
By default, the calendar displays the current week with all its calendar entries.
You can choose to hide the weekends and you can gray out events that are in the past.
Increased detail
If you've got a lot of events, you may want to show a rotating view of only today plus maybe two or three upcoming days!
You can even go vertical with this!
More overview
You can also choose an overview over the next three weeks - albeit at less detail.
If you go vertical, you can even display up to four weeks - though this tends to get crammed unless you hide the weekends.
