Which language are you using for that? You can do it in Javascript or in ASP.NET with (C# or VB). But even better is to just one of the thousands of ready made date pickers that are all over the internet.

On the event of ListBoxMonth.Se lectedIndexChan ged go to a function that checks which month is selected, then populate the ListBoxDays.Ite ms property with the right number of days.

Exactly how you do the populating is up to your programming style. Maybe you have a List with the number of days in each month {31,28,31...} then loop from 1-x adding the loop's index to the Day dropdown list. Maybe you do use a Switch construct (case "January".. . case "February". ..)
