At first, the Calendar application should be added to your Jira. Read how to find, add and manage the Cloud apps (Atlassian documentation).
When the app is installed:
- the user section becomes available (Apps → Calendar)
- the global settings become available (Jira Settings → Apps → Teamlead Calendar)
- two custom fields of the Date Time Picker type are created: Start Date & End Date
- the Calendar gadget becomes available on dashboards
Calendar objects and concepts
The app allows users to create such objects as calendars and switch between them in the user section interface. A user can only browse one calendar at time.
Each calendar displays a scope of issues and events – issues come from Jira projects while an event belongs to a particular calendar in which it was created.
Each calendar requires 2 date-time parameters that will be treated as issue/event start and end marks. A planned issue is one that has both dates specified. Issues that meet the calendar scope but have one or both relevant date-time fields empty are considered unplanned and can be found in the Unplanned Issues section of this calendar.
