//
// This calendar has been modified heavily for integration into Dart.
// For a general javascript calendar, please see the original version
// of this calendar by Robert Husted.
//
// JavaScript Calendar Component
// Author: Robert W. Husted  (robert.husted@iname.com)
// Date:   8/22/1999
// Modified Date: 11/30/1999
// Modified By:   Robert W. Husted
// Notes:  Added frameset support (changed reference for "newWin" to "top.newWin")
//         Also changed Spanish "March" from "Marcha" to "Marzo"
//         Fixed JavaScript Date Anomaly affecting days > 28
// 
// 
// 
// Usage:  Add the following lines of code to your page to enable the Calendar
//         component.
//
//
//         // THIS LINE LOADS THE JS LIBRARY FOR THE CALENDAR COMPONENT 
//
//         <SCRIPT LANGUAGE="JavaScript" SRC="calendar.js"></SCRIPT>
//
//
//
//         // THIS LINE IS USED IN CONJUNCTION WITH A FORM FIELD (myDateField) IN A FORM (myForm).
//         // Replace "myForm" and "myDateField" WITH THE NAME OF YOUR FORM AND INPUT FIELD RESPECTIVELY
//         // WINDOW OPTIONS SET THE WIDTH, HEIGHT, AND X/Y POSITION OF THE CALENDAR WINDOW 
//         // WITH TITLEBAR ON, ALL OTHER OPTIONS (TOOLBARS, ETC) ARE DISABLED BY DEFAULT
//
//         <A HREF="javascript:doNothing()" onClick="setDateField(document.myForm.myDateField);top.newWin = window.open('calendar.html','cal','dependent=yes,width=210,height=230,screenX=200,screenY=300,titlebar=yes')">
//         <IMG SRC="calendar.gif" BORDER=0></A><font size=1>Popup Calendar</font>
//
//
// 
// Required Files:
//
//         calendar.js   - contains all JavaScript functions to make the calendar work
//
//         calendar.html - frameset document (not required if you call the showCalendar()
//                         function.  However, calling showCalendar() directly causes
//                         the Java Virtual Machine (JVM) to start which slows down the
//                         loading of the calendar.)
//
// 
// Files Generally Included:
//
//         calendar.gif  - image that looks like a little calendar
// 
//         yourPage.html - page that contains a form and a date field which implements 
//                         the calendar component
//

// mm   = 1 or 2-digit Month
// MM   = 2-digit Month
// yy   = 2-digit Year
// YY   = 4-digit Year
// yyyy = 4-digit Year
// month   = Month name in lowercase letters
// Month   = Month name in initial caps
// MONTH   = Month name in captital letters
// mon     = 3-letter month abbreviation in lowercase letters
// Mon     = 3-letter month abbreviation in initial caps
// MON     = 3-letter month abbreviation in uppercase letters
// weekday = name of week in lowercase letters
// Weekday = name of week in initial caps
// WEEKDAY = name of week in uppercase letters
// wkdy    = 3-letter weekday abbreviation in lowercase letters
// Wkdy    = 3-letter weekday abbreviation in initial caps
