Introduction
One of the design principles of HistoryCal is that simple things should be simple to do and more complex things should be possible. The hope is that, despite the power of HistoryCal to do almost anything with dates, the user should find using it comes naturally and without the need to refer to this manual too often. If, on the other hand, you do want to do something complex - like create your own calendar variant - you will find what you need here.
