passing the event date in a url

[stewart.campbell]

Can anyone advise how to pass the event date in a URL from the event description.

So far this works fine

<a href="order_card_passdate.php?discount=10.00">10% Discount Today!</a>

I want to add after the discount the date the event date the user has clicked on eg

<a href="order_card_passdate.php?discount=10.00&date= $eDate">10% Discount Today!</a>

Iam trying to integrate the calendar into a shopping cart to discount products based on date purchased.

Can anyone help?
