FatDate provides useful extensions to the Date class including a way to specify dates via a number of rich 'specs', strings that allow specifying dates using calendar-based concepts, such as years, quarters, months, semimonths, biweeks, weeks, and days. Also, provide methods for determining whether a given Date is a federal or NYSE holidays, and more.
