Domain users (Sellers & Buyers) will see 'Events' only if admin configure this feature on the domain.
If the feature is configured, then domain users will see a top level tab "Events". On clicking this tab, Events screen is displayed. As per admin setup widgets will give a view of the upcoming/Featured/Past events. Each of the event tile will display name of the event, date & location. 'View Event' button redirects to the event detail screen.
Display of this screen is dependent on how admin has set it up.
