I do!
1) In Calendar.js file change this line:
dayPanel.setAttribute("data-key", key);
on this:
dayPanel.setAttribute("data-key", calendar[key].year + "-" + ( "0" + calendar[key].month).slice(-2) + "-" + ( "0" + calendar[key].day).slice(-2));
var currentDate = new Date();
jQuery(".dayPanelHeight").each(function() {
var specifiedDate = jQuery(this).data('key');
var date = new Date(specifiedDate);
if(date.setHours(0,0,0,0) == currentDate.setHours(0,0,0,0)){
jQuery(this).addClass('today');
}
});
2) In your .css file add new element with name .today {} and set your own styles for current data.
Thx me!
