Unfortunately, using the same event and editing the details does not work with our platform. If you do this, it will interfere with your payout amount and you may not get the full amount you earned for your event.
However, we do have the ability to clone an event which allows you to duplicate all of the same information but generate a new event. From there, you will be able to edit and change the date and any other information you need without interfering with your payout and revenue from the old event.
See article: How Do I Duplicate an Event for how to do this.
