How to use this date picker in your app:
Put the following 2 lines in your page's <head> section:
<link rel="stylesheet" type="text/css" href="datepicker.css" />
<script type="text/javascript" src="datepicker.js"></script>
On any <input> that you want to have a date picker for, set/add the 'datepicker' class:
<input id='start_dt' class='datepicker'>
<input id='another_dt' class='myclass datepicker'>
I hope you enjoy this date picker as much as I enjoyed getting it to work cross-browsers :)
