Snap Events indicated on the Calendar are reminders of major holidays or upcoming or past SnapRetail webinars. For Webinars, you can click to register if the webinar has not occurred yet or click to view a recording of the webinar if it is from a past date. Major holidays are listed for your reference to plan your marketing around, but are not clickable.
You can turn the Snap Events off so that they do not appear on your Calendar using the checkbox icon to the left of the Calendar. You can turn them back on by checking the box again.
