Drupal for a Theatre Web site

I'm wondering whether Drupal is the right solution for a web site I'm building. It is for a local improv theatre, and will have the following features:

- Event Schedule: Shows, worshops, etc... there will be a page to view all of these, with the currently upcoming weeks events appearing on the home page. Each one will need some type of date attatched to it so that it can be sorted in chronological order.

- Playgroups: These are the different groups that have visited or are planning on visiting the theatre. I'd like to link to these from events.

- A show archive, detailing the shows that have been done, sortable by chronology or by playgroup.

What I'm most worried about is the events. Is there a way to attach a date to a post that is not the date that it was posted on? Everything else seems possible with the taxonomy system.

Thanks,
