+== NSDateCalculations
+
+The goal to this library is to provide an easy interface for doing calculations with dates in Objective C (mac + iphone).
+
+To use, simply drop the NSDateCalculations folder inside your project and require "NSDate+Calculations.h".
+
+Currently implemented methods:
+
+- (NSDate *)beginningOfDay;
+- (NSDate *)beginningOfMonth;
+- (NSDate *)beginningOfQuarter;
+- (NSDate *)beginningOfWeek;
+- (NSDate *)beginningOfYear;
+
+- (NSDate *)endOfDay;
+- (NSDate *)endOfMonth;
+- (NSDate *)endOfQuarter;
+- (NSDate *)endOfWeek;
+- (NSDate *)endOfYear;
+
+- (int)daysInMonth;
+
+More documentation coming soon as the project evolves
