Within Teamwork, you can add events to your calendar to track appointments, meetings, holidays, or other time-specific items.
Events can be added, viewed, and edited from within the site-level Calendar area.
Events can have a start time and a duration of hours and minutes, run all day, or cover multiple days.
Events can be company wide, project specific, or private to you.
Note: Collaborators have view-only access to the calendar. They cannot create events.
