If a PO Box is rented on May 13th, what would be the 6-month renewal due date?

When a PO Box is rented, the rental period is typically for six months. In this case, if the PO Box is rented on May 13th, you simply need to calculate six months from that date to determine the renewal due date.

Counting six months from May 13th brings you to November 13th. However, in practice for PO Box renewals, the due date is often set for the last day of the month in which the rental period ends. Therefore, instead of using November 13th, the renewal due date would adjust to the end of November, as it coincides with how PO Box renewal dates are structured.

As such, the last day of November is November 30th, and that means the correct answer is actually November 30th, indicating that the renewal would be due at the end of the month rather than on the exact six-month mark. Therefore, the correct calculation leads to the conclusion that the renewal due date fits with standard operating procedures used by the USPS.
