The due date, which is stated in the dashboard and your promissory note, is a fixed date that cannot be changed. However, the payment date can be different from the due date. This can be set before or after the due date (Please keep the grace period in mind). Payment date is the date the payment is scheduled on. You can change your monthly payment date by logging into the dashboard, and clicking “Add/Edit Recurring Payments.”  See here for information about how changing your payment date can impact interest accrual.
