validate_date

Many functions expect Dates. 
Determining that they are validly entered is often quite 
computationally costly, relative to the core calculations.
These internal functions provide mechanisms to check validity
quickly, while still providing clear, accurate error messages.

Utilities to cost and evaluate Australian tax policy, including fast
projections of personal income tax collections, high-performance tax and
transfer calculators, and an interface to common indices from the Australian
Bureau of Statistics.  Written to support Grattan Institute's Australian
Perspectives program, and related projects. Access to the Australian Taxation
Office's sample files of personal income tax returns is assumed.
