Date of the next recurring charge. If changed, the next charges will follow this date.
Example: in a monthly interval recurrence, the day of the month on which the charge is made is always the 10th. The first charge was on 10/01/2024, so the next billing would be 10/02/2024. If this next billing date is changed to 20/02/2024, from then on, the next charges will be on the 20th of the month, monthly.
