Why does the 'best date to reduce balance by' date on my dashboard differ from my payment due date?

In the credit utilization section of your MyMarble dashboard you will see 'best date to reduce payment by' when looking at the utilization information on a credit card, as shown in the image below: 

This date differs from your payment due date as this is the date your payment information is next reported to the credit bureau. Reducing your payment by this date will ensure that the new balance on your card will reflect on your next credit report. It's important to note that you should still be making at least the minimum payment on the payment due by date on your credit card statement, and that payments to your credit card can take a few business days to clear.
