Within Teamwork.com, 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, visible to anyone with access to the calendar, project specific, or private to you.
Note: Collaborators cannot access the calendar.
