Using the Date Input Calendar

This is the Open Source Project for Input Date Calendar I came across on code.google.com . Add the Javascript file and the CSS file  to your project. And whenever an input type="date" will be there, the Javascript will be called. And the input for the date will be like this (Image) .

Also Check out this http://simonwillison.net/code/js/date-parser/ . It gives a variety of ways to input dates.
