All Implemented Interfaces:

java.lang.Comparable<WDate>
```
public class WDate
extends java.lang.Object
implements java.lang.Comparable<WDate>
```
Class which holds a date on the gregorian calendar, specified as day/month/year. A valid date may be specified by year, month, and day of month (using the WDate(int, int, int) constructor, or the setDate(int year, int month, int day) method). When attempting to specify an invalid date (with an impossible combination of year/month/date) an IllegalArgumentException will be thrown. The class provides a flexible way for converting between strings and dates. Use toString() to convert to strings, and fromString() for parsing strings. Both methods take a format string, and the same format syntax is supported by both methods. Simple operations are supported to compare dates, or to calculate with dates.
