This is a customizable script that can be modified to suite your requirements in which you need to interact with the customer for providing online appointment and booking service. Once the customer requests you for a booking or appointment, you can plan your schedule and let them know about your status, that whether service would be available at the requested time or not. You can record your events and keep track of them. The script enables you to navigate through days, months and years using the Previous and Next buttons given on top right of the page, giving a look and feel of all standard calendars.
