/*SPECIFYING SHOW DATES:
There are two ways to list dates: 
1. List ea. day individually in the PDaTi array: PDaTi= new Array(new Date("July 20, 2007 20:00"), new Date("July 21, 2007 20:00"), new Date("July 27, 2007 20:00"), new Date("July 28, 2007 20:00"),new Date("August 3, 2007 20:00"), new Date("August 4, 2007 20:00"), new Date("August 5, 2007 18:00"));
2. If all performances are at times (F8, Sa8, Su6): PDaTi[0] = DaTi of Opening night; [1] = "x"; [2] = total number of shows.
3. If events are sequential days all at the same time: PDaTi[0] = DaTi of Opening night; [1] = "xx"; [2] = total number of shows.
