DateBk5 is a replacement calendar for the Palm OS that offers a huge amount of functionality not found in the standard Date Book.
A multitude of views are available, including the To Do List and days appointments, weekly and monthly views, yearly calendar view, and To Do List and appointments for the month.
Should none of these be suitable you can create and save your own view.
Items can be linked so that, for example, you can link an appointment to relevant To Do items or with specific contacts.
DateBk5's TimeZone management ensures that items in different time zones are displayed with adjustments for your current time zone.
Advanced floating reminders ensure you never miss an important date, and hundreds of other features provide greater functionality.
To give you some idea of how powerful DateBk is, the manual comes to over 100 pages.
