Skylight Calendar Profiles are collections of events, tasks, and lists that are assigned to people. Each member of your household can have their individual Profile, so that each can have their own events, tasks and lists. A separate Profile for each member of your household can help keep your Skylight Calendar organized.
Events can support multiple Profiles, so it's often easier to add multiple Profiles to an event, rather than creating a new Profile for a group.
Labels are similar to Profiles, but aren't meant for people: Labels are used for stand alone events that aren't specifically connected to any individual, such as national holidays or sporting events.
