listing dates ranges

I am writing a php front-end to create dynamic queries on a mysql database, and i'm a pretty new programmer! I want to offer the user a date range, and the dates I want to use are stored in my database: 2002-02-17 2002-02-24 2002-03-02 2002-03-09 2002-03-15 ... and I can select them, but what method can i use to list them out in a drop-down side-by-side so the user can select the range? Select date range: 2002-02-17 to 2002-02-24 2002-02-24 to 2002-03-02 2002-03-02 to 2002-03-09 2002-03-09 to 2002-03-15 2002-03-15 to present any help appreciated! thanks, rory
