// wz_ekfeed_month_top2.js 
//
// javascript code to draw small calendar with EventKeeper EKFeed
// also includes Dynamic Drive TOOLTIPS code
// in case you're wondering, there's some code here that isn't really
// necessary but I like the URL month numbers to be standard notation e.g. 
// january = 1, but javascript arrays start with 0 so... fuss, fuss, fuss.
//
// 12/28/2008 fixed year rollover bug

// 04/25/2005 added escape when creating evtArray date
// (added corresponding unescape in wz_tooltip2.js
