Calendar date manipulation

[lrep]

Hello, I am using Jasons Date Imput Calendar to have my visitors enter 2 dates. I have this working OK, but I want to improve the user input. The user enters an order date which is defaulted to toda's date. I want to make sure that the date input is not before today's date. How can I do this? Also, I want to make sure that the second date is 1 day on (tomorrow's date). Anyone one there can help me with this?
