OneNote Time Planner
One of the best options for a daily planner for OneNote users is the OneNote Time Planner by Dean Gardiner. This is a template made available as a free download by its creator.
After downloading and extracting the zip file containing the template, double click on the "TimePlannerTemplate.onepkg" file in Windows Explorer to open the template in OneNote.
When the "Unpack Notebook" window appears, define the desired location for the template or accept the default location and then click the "Create" button. A planner notebook opens with helpful instructions on its use.
If you can, take some time to do a couple house cleaning tasks before jumping in to use the daily planner. First, browse to your notebooks folder and then make a copy of the notebook that was just installed. Browse to C:\Users\[User Name]\Documents\OneNote Notebooks\TimePlannerTemplate\Step 5 - Daily Planning and then copy the "Year 20xx" folder. This will allow you to preserve the generic notebook section for use in future years.
When this is done, open the time planner notebook and then right click on the Year 20xx - Copy and then rename it for the current year.
The other bit of housekeeping is to rearrange the month sections into their chronological order. By default, OneNote sorts these sections alphabetically which is not very convenient.
Because this template includes a daily planner plus a whole framework for implementing a "getting things done" system to get your entire life in order. Of course, if you only want to use the planner part of the template, you can feel free to delete the extra sections.
