OneCalendar

If you are an organized person or you want to become one, you can start off by using an application such as OneCalendar, that helps you remember daily tasks, anniversaries, birthdays, important notes, appointments and other scheduled activities.
OneCalendar is a small-sized software solution that provides you with the ability to search and go through your OneNote entries using a calendar layout.

Quick access and easy-to-use calendar-like display

The interface provides easy navigation and proves to be very intuitive and user-friendly. Unfortunately, it acts only as a gateway to other notebooks, and it comes with a limited set of customization options.
Upon initialization, through the program's calendar view, you can swiftly navigate to the previous or next day, week or month. Plus, you can track your notes from previous years or plan ahead new activities for the upcoming years.

Preview and filter pages

Pages on the calendar view can be filtered if you enter specific keywords. Thus, you are able to quickly find notes by hitting the Ctrl+F keys or by clicking on the search box and start typing keywords.
You can save time precious time by moving your mouse cursor over page titles to get a preview of what those pages are about. Furthermore, you can directly open OneNote contents from within OneCalendar by clicking the page titles that interest you.

Customize the way your calendar is displayed

From the lower right-hand corner of the main window, you can click the gear icon that gives you access to the tool's settings. Next, you can change the font size from very small to extra large, you can choose to display page previews on hover and select to start the week on Monday or Sunday. Also, you can select a notebook of your choosing and display pages both on created or last modified date.

In conclusion

To conclude, this software solution addresses all users and can easily be accessed with the help of keyboard or mouse shortcuts. Although, in order to make it more appealing, the interface could use some improvements.
