Yes. You can change your due date to any day between the 1st and 28th of the month. It's important to note that you can change your due date only once during the life of the Balance Transfer Plan. Any changes won't go into effect until the next billing cycle, which may result in a longer billing cycle and a larger minimum payment because of additional accrued interest.
For example, if your due date for the current month is July 5, and you request to have your due date changed to the 10th of the month, your next due date won't be until August 10. You'll still need to make your minimum payment on July 5.
