To change the start date for a future subscription, navigate to the account in your Recurly site's user interface. From there, in the subscription table of the account go to "options" then, "view subscription." On the following page, you will see the Subscription Actions dropdown menu on the top right-hand side. Clicking there will present several actions that you can take including the option to "Change Start Date." Once you have selected the desired start date and saved the change, you will be redirected to the subscription view where the new date will be reflected.
