Build site using php

This website is an os commerce website of a hotel. People who wants to book their visit have to make their reservation by specifying the date of their visit. The existing site has only one date field for one event. The problem is when the customer wants to book for more than one event on different dates, the option is not available. So to rectify this we need to create a calendar for each event. Tell me if you can create the calendar with more functionalities. The functionalities are: The canlendar should show todays date and should not allow to select a date in the past. Some of the dates needs to be skipped out or deselected depending upon the events (some event may be only on sundays or so).
