We can hide it for you. You can just contact our support team through chat. The session dates and times will still appear, but attendees won't see the event date from the event landing page.
The event date and the add-to-calendar option will also be hidden from attendees' order confirmation emails.
Hiding the event date is usually done if, some days in the event, you have no activity or a hybrid event where the virtual and in-person events start on different days. Hiding it will lessen confusion; you can just add the actual dates in your About tab.
