Calculate Dates for a Week

Hi,

I'm working on a form where the user enters a date in a date field and I would like to write a javascript code to automatically fill in the dates for the rest of the week. So if a user enters 12/16/13 in StartDate field,  four other date fields automatically filll in with 12/17/13, 12/18/13, 12/19/13, 12/20/13 so the user doesnt have to do each one.

I would greatly appreciate any help.

Thanks,
