In some situations, you may need the registration for an event to stay open past the start date, or to close it few days or weeks before. This is easy to accomplish by changing the Registration Close Date & Time on the event setup form to the desired date and time. It defaults to the stat date and time of the event when it is not provided. You will find this option within Step 1 – Main Details of the form, next to the Stat Date & Time field. It can be set to close as early as you like and as far as the end date of the event.
