// 09/21/1998 amp Initial revision.
// 09/28/1998 amp Made the height of the day blocks a minimum of 70 and 
//                centered column headings.
// 11/06/1998 amp Repeated the font specification on each day because 
//                Netscape had a problem with it.  Also placed the entire
//                calendar in a table so I can control the background color
//                so my header and copyright line show up.  
// 11/25/1998 amp Add a row for days 30 and 31 if necessary.  Also made 
//                colors work correctly in past and future.                                     
// 12/09/1998 amp Fixed the color problem permanently.
// 02/16/1999 amp Forced the year to 4 digits.
// 09/21/1999 amp Updated with baja information.
