1.01-02 Use the Model Calendar by default


As the Model Calendar is dynamic, there are a lot of advantages in using it for the majority of modules.  Choose suitable time settings (past and future years) that cover most of the requirements and use the model calendar to set these in the most part.  For the exceptions outside of the “norm” use time ranges for efficiency of calculations and for keeping the model size under control. But remember, Time Ranges may need to be updated manually on a year end rollover.
