Currently, if the client/user wants to choose a different date than the default displayed date, they must press the "select a different date" link and choose the date from a calendar. And if they want to check another date, they need to do that again.

There should just be simple "forward" and "back" buttons to move one day forward or one day back, in addition to a link to select a specific date. 95% of the time a user just wants to scroll forward or back by one day and doesn't need the headache of picking a date from a calendar.

Also, it sure wouldn't hurt to make the date appear in a bigger bold font so that it's more obvious to the user what date they are scheduling (many users don't notice and just assume it is scheduling for today).
