I am in search of a calendar cum day-planner type of a javascript to be used in my project (a day-2-day booking system). The javascript I am looking for is somewhat like this:

Meeting Room Booking System

Note: There is a must requirement of the time-slots table (along with the calendar) given in the lower half of the page.

The script i require is very much similar (rather same ) as shown in the above link (MRBS calendar script).... but i need a javascript and not the one in php.
Thank you for your help.
