How to create recurring calendar events?

I am using asp mvc 3, jquery full calendar, ms sql sever 2008 and c#.

I am wondering if anyone knows how to make recurring events?

I am unsure how to make them.

For instance in google calendar you can make an appointment repeat yearly forever. I doubt that they generate that appointment X times in the database.

I am wondering how I could have one row in my db and somehow know to call that up when needed.

Also google calendar and outlook have lots of repeating options like repeat on the 1st month, last month and etc.

Is there any libraries build that have this? Or do I got to make it from scratch?

P.S

I am on a shared host so a solution has to work with limited rights.
