There are a lot of JavaScript Calendars out there, but actually only a few can be very customizable to fit anyone's need. That's why we have created a Calendar Component that is very customizable and extendable. You can see our Calendar at work right in this page. There are tons of features in this calendar package, such as - Create any numbers of months per calendar. - Set the weekend, days off, holidays (dates off), start day of the week. - Start and end date. - Multi selection with limits or without. - Skinnable (using CSS). - Can have any number of calendars in any page. - Optimized for best performance.
