Why do I have a Maybe calendar?

HEY Calendar automatically includes a 'Maybe' calendar. Events on the 'Maybe' calendar look a little different from events in your other calendars, with hatch shading:

We all have those invites that we're interested in, but can't fully say 'Yes' to, yet. Use the 'Maybe' calendar to add events that you're not fully committed to at the moment, then move them to a different calendar when you are a little more sure.
