// 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
//

// SPECIFY DATE FORMAT RETURNED BY THIS CALENDAR
// (THIS IS ALSO THE DATE FORMAT RECOGNIZED BY THIS CALENDAR)

//
// dd = 1 or 2-digit Day
// DD = 2-digit Day
// 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
// WKDY = 3-letter weekday abbreviation in uppercase letters
//
// Examples:
//
// calDateFormat = "mm/dd/yy";
