Date Options

Hi All,
I want in my survey form two dates. One is, the “date of entering” and the second will be “Date of birth of a child”. Actually, in our survey, it is mandatory to only take children more than 180 days of age. So I want to appear the “date of birth” date former to automatically subtract 180 days from the “date of entering” and the person who is entering in the form should only select date which is 180 days prior to date of entering. I hope I have cleared my point. Thank you for your help.
