If you don't have any open events, you can easily set a customised message in your Events form if a family happens to visit the form.
Navigate to the Forms module, and then select the ellipsis menu alongside the form you want to edit. Select Edit form.

Here you can add a message that'll display when you have no open events:
Note: This message will be replaced by the event form when you have open events.
