Google Calendar View – How to View All 24 Hours for Each Day in Week View Mode Without Scrolling

Effective October 2011, there is a feature in Google Calendar Labs called "Hide morning and night" which lets you minimize the wee hours of the morning and the late hours of the evening if you never have much of anything in them.

Click on the "Settings" gear, then "Labs" and enable "Hide morning and night". When you save it, you'll get additional options in your settings to specify what hours should be considered "night."

When you are making the selection of weeks to show in the mini calendar, you can actually change the month with the mouse wheel while you click and drag (if the cursor is stopped while you use the mouse wheel, it may require moving to another day to pick the new month). This lets you create a calendar view several months long.
