This short 2 page article was a topic spun off from my DateTime Object series. The topic didn't fit in with the series so I created a separate article for it.

In my three part series on developing a datetime object in C++, I discussed the common types of operator overloading [1][2][3]. In this article I'm going to discuss a lesser known operator, the parenthesis operator, more commonly known as the function-call operator. But before I do that, we'll look at the most common situation in which one might implement this operator.
