There are three different types of Calendars in Azendoo, the Personal and Team Calendars, and the Subject Calendars. They work similarly but are based on different data.

All calendars display tasks that are either due dates or planned dates on their respective dates (due dates are displayed by default).

All calendars also display only incomplete tasks by default, but you can display completed tasks as well.

All calendars can be displayed as a monthly or weekly view, monthly is displayed by default. The monthly view allow you to filter tasks displayed by members.

You can create tasks from the calendar view. When you hover your cursor on a date, a small and blue "+" icon follows you around. Click on it to create a new task.

If your calendar displays due dates, the task created will have the due date according to the date. If your calendar display planned dates, the task created will have the planned date accordingly. 

You can drag and drop a task to change its due date or planned date. Grab the task by clicking on it, hold and move your cursor to the date you want and release your click to drop the task on that date, and it will automatically change its due date (or planned date depending on the calendar displayed).  

On the weekly calendar, dragging and dropping a task on another row will change the task assignee, on top of changing the date.

Separators will appear differently than regular tasks in the calendar view. They have lines above and under their label to make them easily distinguishable.
