Adding or subtracting days to a date, or calculating the difference of days between dates are relatively simple operations and there are plenty of components capable of execution such operations.

However, if you want to know for instance to determine on which month will happen the next Friday 13th, that is not such an easy calculation.

This class is capable to perform several kinds of unusual date calculations that may be interesting for specific purposes.
